Question

Write the standard form of the following number:
$0.0000085$

Answer 1

Given decimal number $0.0000085$
Since, we have $7$ digits after the decimal point,
So, we need to multiply by $\frac{{10}^7}{{10}^7}$ to remove the decimal point.

$\Rightarrow 0.0000085\times \frac{{10}^7}{{10}^7}=\frac{85}{{10}^7}$

$\therefore 0.0000085=85\times {10}^{-7}$.
