Write y = 3x as a logarithmic function. Is it x = log3^y?

    Do you mean \(y=3^x\) ?

    log y=log3x log y=log x +log 3

    If it is so, then use the identity: \(\log_aa^b=b\).

    so I don't just turn \[b ^{y} = x\] into \[y = logb ^{x}\]? Then... I really don't know how I'm supposed to write it.

    \(x=\log_3y\).
