need help with2^4 + 2^4 + 3^5 ...... Simplify

I need help with this question:

2^4 + 2^4 + 3^5 +3^5 + 3^5

They somehow simplified it to tthis answer of 2^6 + 3^6

Also another similar question that I was having trouble with was:

2^(x) - 2^(x-2) = 3(2^13) what is the value of x

They got the answer of: 15`
