Exponents

Hi there,

I am trying to solve the problem below but don't know where to go from here. This question appeared on the official GMAT practice test.

Q: Which of the following is equal to the value of 2^5 + 2^5 + 3^5 + 3^5 + 3^5?

OA: 2^6 + 3^6

How would you solve it?

Thank you!

Ksenia

2^5 + 2^5 = 2*(2^5) = 2^6

3^5 + 3^5 + 3^5 = 3*(3^5) = 3^6

so it is 2^6 + 3^6
