# Math Help - Make x the subject

1. ## Make x the subject

Make x the subject of: (a^x)/(b^1+x)=(c^3-x)

I'm assuming it first has to be converted to log form some how. Can't get my head around it though, if anyone could help out that would be great.

Thanks.

Please use parenthesis properly. What you wrote is
$\frac{a^x}{b^1 + x} = c^3 - x$
