Question #d4c38

Answer 1

`ln(x)/ln(7) = ln_7x`

Explanation:

If function f(x) has inverse g(x), then f(g(x)) = x.

`ln_7(7^x) = x`. By the change of base rule, this transforms to `ln(x)/ln(7)`

These exponentiation ones can be tough, so be careful! I messed this one up my first and second tries!

GOOD LUCK
