2. Factor these

---(3x^11z^5)^3
b. (3x^5)^ -3 / 2x-5(3y)^4
c.3x^5)^ -3 / 2x ^ -5(3y)^4
(same as b but - 5 is the exponent)

What is part (a)?

It looks like you omitted a ^ in (b). Without a ^ before the -5, it cannot be factored.

It does NOT look like you want these factored. It looks like you want them simplified by multiplication or division.
