Try to break up the problem into smaller pieces.
For example, 54+5=59, so can you make 41 from 3,5,6,2?
If not, try using 54-5=49. See if you can make 51 from 3,5,6,2.
You are allowed to use exponents, for example, 6^2=36.

If you can make 51 from 3,5,6,2 then the result will be
I also gave you the hint that 6^2=36, that means you need to make 15 with the rest.
