Aug 11, 2016

$8.97 \times {10}^{- 3} = 0.00897$

Explanation:

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

$8.97 \times {10}^{- 3}$ means 8.97 divided by 10 three times to get a small decimal.

$8.97 \times {10}^{- 3} = 0.00897$

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.
