Question

9*-0^2 is blank times as much as 3*10-^2

Answer 1

Explanation:

As I understand the question you have the following expressions given in scientific notation:

Expression A:

$9\times10^2$

Expression B:

$3\times10^{-2}$

So we need to compare both expression in order to know how much times is expression A bigger than B. So:

$\frac{9\times 10^2}{3\times 10^{-2}}=\frac{9}{3}\times10^{2-(-2)}=3\times 10^4=30,000 \\ \\ \\ *\frac{a^n}{b^m}=a^{n-m}$

In conclusion $9\times10^2$ is $30,000$ times as much as $3\times10^{-2}$
