Step-by-step explanation:
Given
--- inverse
Required
For two functions f(x) and g(x) where f(x) and g(x)are inverse;
So, by comparison:
k =
using the ' laws of logarithms '
log x - log y = log ( )
logx = logy ↔ x = y
logk - log(k - 2) = log5
log ( =log 5
= 5
5(k - 2) = k
5k - 10 = k
4k = 10 ⇒ k = =
