Question

calculate.
\frac{6\times 10^{9}}{2\times 10^{5}}
write your answer in scientific notation.

Explanation:

Step1: Divide the coefficients

$\frac{6}{2}=3$

Step2: Divide the powers of 10

According to the rule $\frac{a^m}{a^n}=a^{m - n}$, $\frac{10^{9}}{10^{5}}=10^{9 - 5}=10^{4}$

Step3: Combine the results

$3\times10^{4}$

Answer:

$3\times10^{4}$
