Question

What is 6 million written in scientific notation?

Answer 1

Hint: First of all one million has 6 zeros, so 6 million can be written as $6000000$. Now, scientific notation means we have to express a very large number as a number between 1 and 10 multiplied by a power of 10.
$m\times {10}^n$, where m is between 1 and 10.
So, we have to express 6 million in $m\times {10}^n$ form, which is discussed below in detail.

Complete step by step solution:
In this question, we have to write the scientific notation of 6 million.
First of all, what does scientific notation mean?
Scientific notation is used to express very small or very large numbers efficiently. A number is expressed in scientific notation as a number between 1 and 10 multiplied by a power of 10.
Hence, numbers in scientific form are written as
$\Rightarrow m\times {10}^n$, where m is between 1 and 10.
For example: 350000 can be expressed as $3.5\times {10}^5$ in scientific notation.
Now, we have to express 6 million in scientific notation.
Now, a million has 6 zeros and hence 6 million can be written as $6000000$.
Here, $m=6$ and $n=6$.
Therefore, 6 million in scientific notation will be $6\times {10}^6$.

Note:
We can similarly convert a scientific form number into a decimal form number as we did above.
To convert a number from scientific form to decimal form, write m followed by n zeros.
For example: $6\times {10}^6$
Here, $m=6$ and $n=6$. Therefore the decimal form will be $6000000$.
