2.5 X 10(-2 exponent) compared to 2.5 / 10(+2 exponent)

the answer is =. I can't figure out how to divide the last part.

2.5 X 10(-2) = 0.025 ( i think)

2.5 / 10(+2) = ?

I hope you can help.

\(\displaystyle \L \frac{2.5}{10^2} = \frac{2.5}{100} = .025\)

the point is ... \(\displaystyle \L 10^{-2} = \frac{1}{10^2}\)
