There isn't a problem here, it's an example they gave, but I don't get how you can get the answer without using logs.
2^(2x+1) = 1/32
2^(2x+1) = 2^(-5)
How do they know that it's -5?
Same thing for:
3^(x-1) = 27
3^(x-1) = 3^3
Is it just trial and error? I've tried a bunch of different methods but none have worked.
