Question

divide. write your answer in scientific notation.
\frac{2\times10^{-3}}{1\times10^{-1}}

Explanation:

Step1: Divide the coefficients

Divide 2 by 1: $2\div1 = 2$

Step2: Divide the powers of 10

Use the rule $\frac{a^m}{a^n}=a^{m - n}$, so $\frac{10^{-3}}{10^{-1}}=10^{-3-(-1)}=10^{-3 + 1}=10^{-2}$

Step3: Combine the results

The result in scientific - notation is $2\times10^{-2}$

Answer:

$2\times10^{-2}$
