Which choice is equivalent to (4^2)(4^3)?
A: 4^6
B:4^5
C:64
D:16

Correct me if i'm wrong, but i think it's b, since you add the exponents and keep the 4 the same.

B. 4^5

When multiplying exponents with the same base, you can simply add them together and keep the base the same.
Many people accidentally multiply the exponents, so just be cautious of that :) hope this helps

These are the multiples of 15 but what you are probably asking or what are the factors of 15
