Here is a tricky problem that I saw on GMAT Prep

C = 2 ^ 25

R = C ^ C

What does R = ?

It is actually a concept I saw on an actual GMAT. I changed the variables and the numbers to comply with the rules of this site.

Just want to know how to do it.

C = 2^25
R = C^C
I can't do this on Windows XP Home edition because the answer is too large.
We could make the problem a lot simpler if we change 25 to 3. That should not change the process for solving.
C = 2^3
R = C^C

C = 2^3 = 8
R = C^C =8^8 = 16,777,216

This seems to easy. Don't trust the answer until a moderator or someone who knows what they are doing, checks it.

We appreciate your efforts to follow our forum's guidelines.

Would love to help you with this problem, but this appears to be a number properties problem where the correct solution depends greatly on how the answer choices are expressed. Without those, it's hard to know which path to take.
