so far I have
log 4^x+5 = log 6
(x+5)log 4 = log 6
not sure where to go from here, any help is appreciated

Solve for x:
First, you ought to use parentheses to show that the exponent is (x+5).
Take the logarithm of both sides.
Apply the power rule to the left side.
Divide both sides by
Evaluate the right side.
Subtract 5 from both sides.

At first, because you have no parentheses in 4^x+5 = 6, I assumed that the problem was:
If this is what you really meant to write, then: Subtract 5 from both sides.
Take the log of both sides.
Apply the power rule to the left side.
Divide both sides by
But , so...
