Integers As Exponents

Integer exponents, mathematically refer to those exponents that should be integers whether positive integers or negative integers. The positive integer exponents denote the number of times a number should be multiplied by itself. The negative exponents as a rule need to first be flipped and then multiplied.

What are Integers?

Did you know that the word integer is derived from the Latin word integer meaning whole? Integers refer to a number that can be represented as a non-fraction. That is numbers that can be written without a fractional component are defined as an integer.

Net gears can be positive or negative.Examples of integer are- 1, 4, 9, -7, -66, etc.

What are Exponents?

Exponents represent the mathematical operation of exponentiation. Exponents of a number show how many times a number should be used in multiplication whether with itself or with other numbers.

For example, 23, where 3 is the exponent and means that two should be multiplied with itself three times.

Integers and Exponents

Simply put, all integers can be exponents-whether positive or negative. Exponents denote the number of times a base number should be multiplied whether with itself or with another number.

For example, the expression 5 × 5 can also be written as 5². The integer here is both 2 and 5 but the exponent is 2. The exponent 2 here denotes that 5 has to be multiplied twice with itself.

Similarly, 4³ stands for 4 × 4 × 4 HD shows that 4 should be multiplied with itself three times.

Integer Exponents Rule

Seven major exponents rules are the answer to the question-“how to solve integer exponents”. These rules are all-encompassing in terms of mathematical operations such as addition, multiplication, division, etc.

Let us understand these rules properly:

1. Product of Powers Rule

When two bases of the same number are to be multiplied, add the exponents while keeping the base number the same.

For example- 32 × 34 = 32+4

= 36

= 3 × 3 × 3 × 3 × 3 × 3

= 729

2. Quotient of Powers Rule

When two bases with the same number are being divided, subtract the exponents while keeping the base the same.

For example-  46 divided by 42 = 46-2

= 44

= 4 × 4 × 4 × 4

= 256

3. Power of a Power Rule

When an exponent is being raised to another exponent, multiple the two exponents and keep the base the same.

For example- (52)3 = 56

= 5 × 5 × 5 × 5 × 5 × 5

= 15,625

4. Power of a Product Rule

When two bases are being multiplied by the same exponent, distribute the exponent to each of the bases.

For example- (41 × 51)2 = 42 × 52

= 16 × 25

= 400

5. Power of a Quotient Rule

When a power is raised to a quotient-distribute it evenly to both the denominator and numerator.

For example- (⅘)2 = 42/52 

= 16/25

6. Zero Power Rule

Any base raised to the power of zero is equal to one.

For example- 30 = 1

7. Negativity Content Rule

When any base is raised to a negative exponent, turn the number into a fraction and then make it reciprocal.

For example- 3-2 = 1/32

The idea behind this rule is to convert the negative exponent to make them into positive ones.

How to Solve Integer Exponents?

Solving integer exponents can be a very easy task if the student is clear with the basics of this concept. As we have explained above Integer exponents are exponents that stand for an integer both negative and positive and denote the number of times the base number should be multiplied with itself or with another number.

Seven rules govern the solving process and all of them have been mentioned by us above. It is through the use of these rules that integer exponent questions can be solved.

Let us look at the general steps of solving such questions-

• Step 1. Carefully look at the question.

• Step 2. Discern which of the seven formulas would be suitable.

• Step 3. Use the chosen formula.

• Step 4. Write the answer clearly.

• Step 5. Recheck the process and the final answer.

The entire process of employing one of the formulas, finding the answer, and then re-checking would make sure that there is no scope for mistakes and if done they can be corrected. Such a strategy would help make you score high marks and avoid silly mistakes.
