Question

2,181x 10 to the power 7

Answer 1

21,810,000,000

Explanation:

Given the following question:


`2181*10^7`

To find the answer we have to remember that all numbers have an invisible decimal point on the right side of the number. To convert a scientific notation into standard form we look to see if the exponent is positive or negative. If positive we move the decimal point to the left, if negative move the exponent to the right.


`2181*10^7`

`2181=2181.`

`+7`

`2181.=2181.0.0.0.0.0.0.0.=21810000000`

`=21810000000`

Which means your answer is "21,810,000,000!"

Hope this helps.
