    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.)
