This confuses me. Can you help for a medal? What is the simplified expression for 5^-3 • 2^2 • 5^5 over 2^3 • 5^2 2^2 over 5^2 5 over 2^2 5 over 2 5^2 over 2

    Wouldn't it be C?

    There seems to be a typo. I'm getting a different answer which isn't in the list of choices.

    5^(-3)*2^2*5^5 = 100 2^3*5^2 = 200 100/200 = 1/2

    you're absolutely sure the problem is 5^-3 • 2^2 • 5^5 over 2^3 • 5^2 ? can you post a screenshot?

    But they want the simplified fraction, not fully solved

    ok so yeah, it looks like \[\Large \frac{5^{-3}\cdot 2^2 \cdot 5^5}{2^3 \cdot 5^2}\] but the problem is that none of the answer choices come up This is what I get \[\Large \frac{5^{-3}\cdot 2^2 \cdot 5^5}{2^3 \cdot 5^2}\] \[\Large \frac{5^{-3+5}\cdot 2^2}{2^3 \cdot 5^2}\] \[\Large \frac{5^{2}\cdot 2^2}{2^3 \cdot 5^2}\] \[\Large \frac{2^2}{2^3}\] \[\Large \frac{4}{8}\] \[\Large \frac{1}{2}\] So strange how 1/2 isn't in the list

    I'm not sure. Any seem likely as to what they meant to say. You'll have to ask your teacher about it since s/he will know what to do. Most likely, the teacher will give you free points back for this one since it's unfair
