Question

⑩ $\frac{5.6\times10^{-3}}{3.7\times10^{5}}$

Explanation:

Step1: Divide the coefficients

$\frac{5.6}{3.7}\approx1.51$

Step2: Divide the powers of 10

According to the rule $\frac{a^m}{a^n}=a^{m - n}$, we have $\frac{10^{- 3}}{10^{5}}=10^{-3 - 5}=10^{-8}$

Step3: Combine the results

$1.51\times10^{-8}$

Answer:

$1.51\times10^{-8}$
