Question 118828: 2^400 divided by 2^396 minus 2^3 = ?
i already solved 2^3 it equals 8, but i can't figure out how to solve the other exponants because it doesn't work on my calculator, and i tried but can't do it by hand, because i can't multiply 2, 400 times it would take hours. also i don't know how to divide exponants, since i can't figure out how to solve them.

You are right, if you do it the hard way, but let's try the smart way!
Evaluate:
I hope I've got this right?
Remember that when you do division with exponents, you subtract the exponents as long as the bases are the same, as in your problem:
=
So now the problem is:
=
