I've never come across a calculator that can't handle exponents right if your input is correct. Edit: and yeah you surely are going to calculate 10-digit numbers in your head.

Lol you're missing the point of the problem entirely. The teacher obviously doesn't expect people to calculate 10 digit numbers in their head. The point is to show students that awful looking equations can be simplified by using prime factorization. There's tons of problems in higher math that look impossible at first glance, but become manageable when you rearrange them or express them a different way. It's a good lesson.
