Hi there,

This question is a bit weird lol, but anyway here is how to do it and the answer:

1/5 = 123² x
1/5 = 15625x
15625x = 1/5

Hence, X = 1/5

Hope this helps :)

This is a log equation. To solve

125^x = 1/5
x log 125 = log 1/5
x = log (1/5) /  log 125
[tex]x = -\frac{1}{3} [/tex]

To show that we are correct. Input -1/3 for x [tex]125^{-1/3}[/tex] with a calculator and it will = 1/5, meaning it is correct.

[tex]125^{-1/3} = \frac{1}{5}[/tex]
