Math Help - Solving for Exponents as Variables

1. Solving for Exponents as Variables

I have the equation $Value = 6(0.92)^n$
I need to know what the cost will be when the Value is 1

So I did this

$Value = 6(0.92)^n$
$1 = 6(0.92)^n$
$1/6 = 0.92^n$

I'm stuck there. Any help is appreciated!

Hint: $\log_{10} \left ( 0.92 ^n \right )$ is what?

(or you could use ln just as easily.)
