## Are you Charged Enough to be a Power of Ten?

The power of ten in mathematics is defined as any of the integer powers of a number multiplied by ten. To put it another way, we add ten to itself, a specific number of times (when the power is a positive integer). Also, the number 1 is a power of ten (the zeroth power) in its definition. In this article, you will understand the power of ten, its facts, converting numbers in the power of ten, & Scientific Notation Regarding the Power of 10. So, let us start by understanding the power of ten in the coming section.

### Power of Ten

In Mathematics, the power of 10 is any whole-valued (integer) power of the number 10. In other words, the power of 10 states that the 10 multiplied to itself n number of times (when the power is any positive integer). Hence, the 10 power in long-form is the number 1 followed by n zeroes where n is the number that is greater than 0. For example, 10⁷ is written as 1,00,00,000.

When n is the number that is smaller than 0, the 10 power is found by multiplying the base value 10 ‘n’ times in the denominator and placing 1 in the numerator. For example, 10⁻³ is written as

\[\frac{1}{10*10*10}\] = 0.001

When n is equal to 0, the power of 10 is equal to 1. For example, 10⁰ = 1.

### How to Convert Numbers in Power of 10 Maths?

To convert any number into the power of ten Math, two basic rules are followed.

1. If the number is given in the decimal notation, move the decimal point to the right side of its original position and place the decimal point after the first non zero digits. The power ten will be the number of places the original decimal point was moved and it will be negative as it was moved towards the right side.

**Example: ** 0.0000732 = 7.32 x 10⁻⁵

2. If the whole number greater than 10 is to be changed into the power of 10 Math, then move the decimal point to the left side of its original position and place the decimal point after the first digit. The power of 10 will be the number of places the original decimal point was moved and it will be positive as it was moved towards the left side.

**Example:** 145,000 = 1.45 x 10⁵

### Multiplying and Dividing By Positive Power of 10 Maths

**1. When multiplying the number by the power of 10, we move the decimal points to the right side for each power of 10.**

**Example:**

62.54 x 10¹ = 625.4

Here, the decimal point is shifted by one place to the right side.

62.54 x 10² = 6254.

Here, the decimal point is shifted by one place to the right side.

**2. When dividing the number by the power of 10, we move the decimal points to the left side for each power of 10.**

62.54 ÷ 10¹ = 6.254

Here, the decimal point is shifted one place to the left side.

62.54 ÷ 10² = 0. 6254.

Here, the decimal point is shifted two places to the left side.

### Multiplying By the Negative Power of 10

Negative power tells how many times to divide the base number. When multiplying the number by the negative power of 10, we move the decimal points to the left side for each power of 10.

**Example:**

6 x 10⁻³ = 6 x 1/10 x 1/10 x 1/10 = 6/1000 = 6 x 0.001 = 0.006

6.1 x 10⁻³ = 6.1 x 1/10 x 1/10 x 1/10 = 6.1/1000 = 6.1 x 0.001 = 0.0061

### Scientific Notation Regarding Power of 10 Maths

The scientific notation, also known as the standard form, was given its name because it was first used by scientists to represent extremely small and large numbers. Exponents refer to the power of 10 multiplied by another number. Moreover, we can find them in both positive and negative forms.

Additionally, the positive form denotes multiplication, while the negative form represents division. The index of ten indicates how many places the decimal points should be moved to the right in the notation.

In scientific notation, the numbers are represented in the form of a x 10ⁿ, where the variable a is the decimal with 1 ≤ a < 10ⁿ, and n is the integer.

To understand this, consider multiplying 1.35 by 10 to the fourth power. Alternatively, 1.35x10⁴.

You can then calculate it by 1.35 x (10 x 10 x 10 x 10), or 1.35 x 10,000, to get the answer 13,500. Now, if we shift the decimal place to 1.35 over four places, we get 13,500.

**Example:**

Avogadro's number in scientific notation is approximately written as 6.022141793 x 10²³. Here a is the decimal 6.022141793 and n is the exponent 23.

### Facts to Remember

A power 10 with a positive exponent such that 10⁴, means that the decimal point is shifted towards the left.

A power 10 with a negative exponent such that 10⁴, means that the decimal point is shifted towards the right.

## FAQs on Power of Ten

**1. What is the Power of 10?**

The power of 10 is the number of places the decimal point can be moved to express any number as a product of 10. The positive power 10 shows that the decimal point is moved to that number of places on the left side. The negative power 10 shows that the decimal point is moved to that number of places to the right side.

**2. What Pattern Does the Power of Ten Maths Follow?**

If you carefully observe then you will find that the number of trailing zeroes in the solutions is equal to the exponents. For example, if the power of 10 is 3 then the answer is 1000 which has 3 zeroes. Similarly, if the power of 10 increases to 6 then the answer 1,000,000 has 6 zeros.

**3. What Does Scientific Notation Mean?**

Scientific notation is a way of representing very large or small numbers conveniently. For example, instead of writing 0.0000000046, we write 4.6 x 10-9. Scientific notation is widely used by Scientists, Engineers, and mathematicians because it simplifies certain arithmetic operations.

**4. How to write scientific notation?**

We rewrite a regular number as a decimal, then multiply it by a power of ten to convert it to scientific notation. For any number, there are an endless number of ways to do it, but we always choose the one with only a single digit in front of the decimal point.

**Example:** In scientific notation, there is an unlimited number of ways to write the number 1879!

1879 = 0.01879 × 100,000 = 0.01879 × 10⁵

= 0.1879 × 10,000 = 0.1879 × 10⁴

= 1.879 × 1000 = 1.879 × 10³

= 18.79 × 100 = 18.79 × 10²

= 187.9 × 10 = 187.9 × 10¹

= 1879 × 1 = 1879 × 10⁰

= 18,790 × 0.1 = 18,790 × 10⁻¹

= 187,900 × 0.01 = 187,900 × 10⁻²

= 1,879,000 × 0.001 = 1,879,000 × 10⁻³

Scientists, on the other hand, prefer "1.879×10³" because:

It has only one digit before the decimal point, allowing for an accurate representation of the number of significant figures.

It is compact, with no extra, unnecessary zeros that are difficult to read and write.

It conveniently tells you at a glance that the number is of the same order of magnitude as 103 (a thousand).

**5. Is it possible to write each decimal as a power of 10?**

Each decimal can be written as a power of ten. The way we estimate light-years, or the distance travelled by light in a year, is spoken using scientific notation rather than writing down the entire numerical representation, which is a practical example of 10s power.

**6. Describe the negative power of 10.**

We have all faced cases when the power of 10 is a negative number. This also means that the integer should be divided by the negative power. For instance, multiply 6 by 10 to the power of three (or 6 ÷ 10-3). This can now be written as 6 ÷ (10 ÷ 10 ÷ 10) or 6 ÷ 1,000. We can then simply move the decimal place three spaces to the left. So, the numerical result of dividing 6 by 10 to the negative power 3 is 0.0006, and this is the answer to the question.
