Ok the first thing you should try to do here is look for ways to simplify this.

(2^5) + (2^5) can be written as (2) * (2^5), which can be written as (2^1)*(2^5), which is 2^6.

(3^5) + (3^5) + (3^5) can be written as (3) * (3^5), which can be written as (3^1)*(3^5), which is 3^6.

Hence the answer 2^6 + 3^6.

Hope this helps.
