Question

divide.
$\frac{5\times 10^{4}}{5\times 10^{1}}$
$1\times 10^{7}$ $1\times 10^{5}$ $1\times 10^{3}$ $1\times 10^{9}$

Explanation:

Step1: Divide the coefficients

$\frac{5}{5}=1$

Step2: Divide the powers of 10 using exponent rule $\frac{a^m}{a^n}=a^{m - n}$

$\frac{10^{4}}{10^{1}}=10^{4 - 1}=10^{3}$

Step3: Combine the results

$1\times10^{3}$

Answer:

C. $1\times 10^{3}$
