GRE Quantitative Reasoning QUESTION #8112
Question 1

The number $0.01$ is how many times as great as the number $(0.0001)^2$?

  • $10^2$
  • $10^4$
  • $10^6$✔️
  • $10^8$
Correct Answer Explanation

$(0.0001)^2 = (10^{-4})^2 = 10^{-8}$

$0.01 = 10^{-2}$

$\dfrac{0.01}{(0.0001)^2} = \dfrac{10^{-2}}{10^{-8}} = 10^{-2-(-8)} = 10^6$

So $0.01$ is $10^6$ times as great as $(0.0001)^2$.
