# How do you calculate (6.3times10^3) div (2.5times10^8)?

Oct 4, 2016

$2.52 \times {10}^{-} 5$

#### Explanation:

Consider $\frac{12 \times {x}^{3}}{8 \times {x}^{8}}$

simplify the numbers $\rightarrow \frac{3}{2} \times {x}^{-} 5 \leftarrow$ subtract the indices

Do exactly the same with $\frac{6.3 \times {10}^{3}}{2.5 \times {10}^{8}}$

simplify the numbers $\rightarrow 2.52 \times {10}^{-} 5 \leftarrow$ subtract the indices.

Note: usually we would not leave an answer with a negative indexm but as we are dealing with scientific notation, in this case we do.
