A classmate asks you to check their answer to this problem:

Simplify: (x^2 y^3)^3 + (x^3 y^3)^0

They got x^6 y^9 as their final answer. Are they correct?

A. No, the whole expression should equal 1 because of the 0 exponent.
B. No, they should have added the exponents instead of multiplying them x^5 y^3 + x^3 y^2
C. Yes, this answer is correct.
D. No, the second term should be 1 after being raised to the power of 0. x^6 y^9 + 1

The correct answer is D. No, the second term should be 1 after being raised to the power of 0. x^6 y^9 + 1
