To determine how many times greater \( 6 \times 10^4 \) is than \( 6 \times 10^2 \), we can set up the following calculation:
\[ \frac{6 \times 10^4}{6 \times 10^2} = \frac{10^4}{10^2} \]
Using the properties of exponents, we can simplify \( \frac{10^4}{10^2} \):
\[ \frac{10^4}{10^2} = 10^{4-2} = 10^2 = 100 \]
Thus, \( 6 \times 10^4 \) is 100 times greater than \( 6 \times 10^2 \).
So the correct response is:
100
