Question

Write y = 3x as a logarithmic function.

Is it x = log3^y?

Answer 1

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

Answer 2

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

Answer 3

yeah I meant \[y = 3^{x}\] sorry didn't type it right.

Answer 4

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

Answer 5

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.

Answer 6

\(x=\log_3y\).

Answer 7

oh thanks
