Question

(\frac{6.6\times10^{-16}}{6.63\times10^{-34}}=)

Explanation:

Step1: Divide the coefficients

$\frac{6.6}{6.63}\approx0.995$

Step2: Divide the powers of 10

According to the rule $\frac{a^m}{a^n}=a^{m - n}$, we have $\frac{10^{- 16}}{10^{-34}}=10^{-16-(-34)} = 10^{18}$

Step3: Combine the results

$0.995\times10^{18}=9.95\times10^{17}$

Answer:

$9.95\times10^{17}$
