Strategic Advice: Raising large numbers to high powers is very time-consuming without a calculator. Instead, start by using the rules of exponents to simplify expressions written in the same base. Then raise any remaining numbers to the resulting powers.

Getting to the Answer: The power of 25 is larger in the denominator, so subtract the exponents there. Then simplify further if possible:, which is (B).
