    logs into exponential form

    I'm working on a problem in class and I'd like help on how to make the function equal to x. The function is f(x)=3 log(x)-1 and I've gotten it to y+1=3 log(x) but I'm not sure what to do with the 3. Help?

    y+1 = 3\log{x}

    \frac{y+1}{3} = \log{x}

    now change to an exponential

    So, it would be 10^(y+1/3)=x?
