Question

How do you express `8.97*10^-3`?

Answer 1

`8.97 xx 10^(-3) = 0.00897`

Explanation:

This is written in scientific notation. It is easier than writing very big or very small numbers which have lots of zeros.

`8.97 xx 10^(-3)` means 8.97 divided by 10 three times to get a small decimal.

`8.97 xx 10^(-3) = 0.00897`

Numbers in scientific notation only have one digit before the decimal point.

A positive index of 10 means multiplied by 10 while a negative index of 10 means divided by 10.
