Question

Simplify.
(2z^5)^3

Answer 1

Would the answer be:
2z^15 OR 6z^15

Answer 2

How did you arrive to those answers?

Answer 3

Because aren't you supposed to multiply the exponents to get 15? But than im confused as to if im supposed to multiply the 2 also or leave it.

Answer 4

You need to elevate everything to the cube. So it is like 2^3 * (z^5)^3. When there are exponents, you multiply 5 times 3. But in the normal numbers (2), you elevate the number to the cube. So 8z^15

Answer 5

Okay got it now! Thank you so much! The cubing part is what confused me :)

Answer 6
