This type of question is kiiiiiling me right now.

Solve for x.

2^(1-x) = 3

Solve for x.

3^(2x-1) = 5

EDIT: these two are similar ones I can't find a solid approach to.

log base 2 of (log base 3 of (x)) = 4

and

10^5^x = 3

I thought I would brush up on my exponents and logs before I did the exponents and logs chapter in my calculus text, but I can't remember how to solve this kind of thing, thank you!
