Question

I need help simplifying this.

(4xy^2)^3(xy)^5

A.64x^8y^11
B.64x^15y^30
C. 12x^2y^11
D. 12x^8y^11

Answer 1

\[(4xy ^{2})^{3}(xy)^5\]
Use exponent properties-When there is a power to a power, you multiply it. When there is a power times another power, you add the numbers.
Try simplifying the first set first... Do 4^3, x^3, and (y^2)^3
