A classmate asks you to check their answer to this problem:
Simplify: a^3 b^5 a^2 b^−3
They got a^6 b^−15 as their final answer. Are they correct?
A. Yes, this is the correct answer.
B. No, the answer is not correct. When the bases are being multiplied, you need to multiply the exponents.
C. No, the answer is not correct. When the bases are being multiplied, you need to add the exponents.
D. No, there should not be negative exponents. The final answer should be a^6/b^15
