Find the product: (4k^5)(-2k)^3
Is it -32k^8 or -32k^2
I don't know rather to add or subtract the 5 & 3.

The correct answer is -32k^8
- When you multiply powers with the same base, you keep the base and ADD the exponents.
- For the second multiplier, note that the both the -2 and the k would be cubed, whereas in the first multiplier only the k get raised to the 5th.
so you would (4)(k^5)(-2)^3 (k^3)
= (4)(k^5)(-8)(k^3)
= -32 k^8
