The answer is negative 32 y^15 or -32 y^15

The first step to do is to multiply the power 5 x 3
then, you will have -2^5 this will give you the value of -32

(-2y^3)^5 = (-2^5y^15)
= -32y^15

the final simplified answer is -32y^15

Recall... (ab)^m = a^m * b^m, and (a^n)^m = a^nm.

(-2y^3)^5 = (-2)^5 * (y^3)^5
= -32y^15.

I hope that helps. :)

(-2y^3)^5
= (-2^5)(y^3)^5
= [-32][y^(3 * 5)]
= [-32][y^15]
= -32y^15
