Almost. : )
You appear to have missed the negative sign in the second bracket.

There is a mistake in sign.
{125(a + b)^25} / {- 25(a + b)^20}
= - (125/25) * {(a + b)^25 / (a + b)^20}
= - 5(a+ b)^5
{125(a + b)^25} / {- 25(a + b)^20}
= - (125/25) * {(a + b)^25 / (a + b)^20}
= - 5(a+ b)^5

You are correct. You divide the numbers and subtract the exponents to get your answer.
