which do you think is wrong?
b cannot be equal to -b. so what I did must have some type of error.
why cant it? a^b = 1 a^(-b) = 1 therefore a^b = a^(-b)
according to a property \[\text{ if} \; a^m = a^n \; \text{then} \; m = n\] are you familiar with that?
yes. but if b = 3 then how can 3=-3 be true
