Yes i can

#

But base negative?

worthy dagger
#

it usually results in complex outputs but yea it could be negative

#

i mean for integers it works fine, for all reals it gets messy

worthy dagger
#

the problem is when you’re doing like
through basic definition we want the base a raised to some power to be equal to b
so if a is negative and as long as c is like an integer we don’t get confused on if it’s positive or negative or whatever

#

i actually dunno how they define that

,w log_(1/3) 81

,w log_(-1/3)81

@worthy dagger

#

(-1/3)^x = 81

#

(-3)^-x = 3^4

#

now times both sides by (-3)^x

#

(-3)^-x * (-3)^x = 3^4 * (-3)^x

#

oh

#

I don't think this works

#

I guess you can consider different cases where x is odd, even and a fraction

#

and verify your solution
