Homework Statement


Ok, so our professor gives us homework online which we submit online, its called webwork. This one equation I found the derivitive of. Heres the thing, the program will not evalute answers with log base other than 10.

Homework Equations


The equation is:
[tex]y=4^xlog_{9}(x)[/tex]
This is the derivitive
[tex]4^xln(4)log_{9}(x)+\frac{4^x}{xln(9)}[/tex]



The Attempt at a Solution


How do I express this by having no logs?
