Question

divide.
\frac{8\times10^{-8}}{2\times10^{-6}}
4\times10^{-2}
9\times10^{-2}
7\times10^{-2}
5\times10^{-2}
submit

Explanation:

Step1: Divide the coefficients

$\frac{8}{2}=4$

Step2: Divide the powers of 10

Using the rule $\frac{a^m}{a^n}=a^{m - n}$, we have $\frac{10^{-8}}{10^{-6}}=10^{-8-(-6)} = 10^{-2}$

Step3: Combine the results

$4\times10^{-2}$

Answer:

$4\times 10^{-2}$
