Which of the following expressions is equivalent to a9 - b9?

1 answer:

8 0

When you have the power multiplied to another power you have to multiply
so
(a^3)^3 - (b^3)^3 = a^9 - b^9

A is correct.

B is incorrect because when you multiply the exponents you get a^18 - b^18

C is incorrect because when you distribute the 2 you get a^6 - b^6

D is correct too
