From the logarithm equation below, can you determine what is the expression for y?

**log y =**

**x + log x**

You may give your answer in the comment section and also help explain how you get it (for the sake of sharing).

Thanks ^^

Take the exponential of both sides you get

exp(logy)=exp(x+logx)

y=exp(x).exp(logx)

y=x.exp(x)

Hi Ali,

I suppose "log y" has the number base as 10. I was expecting the answer to contain a "10" within.
