Question

divide.
$\frac{1.89\times10^{-1}}{1.8\times10^{2}}$
$4.88\times10^{-3}$ $4.88\times10^{0}$ $1.05\times10^{0}$ $1.05\times10^{-3}$

Explanation:

Step1: Divide the coefficients

$\frac{1.89}{1.8}=1.05$

Step2: Divide the powers of 10

Using the rule $\frac{a^m}{a^n}=a^{m - n}$, we have $\frac{10^{-1}}{10^{2}}=10^{-1-2}=10^{-3}$

Step3: Combine the results

$1.05\times10^{-3}$

Answer:

$1.05\times 10^{-3}$
