On my exam, we had to find the derivative of 4^x. This is what I did(adsbygoogle = window.adsbygoogle || []).push({});

Y=4^x

lny=xln4

y=e^xln4

and then finding the derivative for that I got, (xe^(xln4))/4

My professor said that it was wrong and even after I told her what I did to get the answer. She told me the answer was (4^x)ln4 . Which I know it is but I think this is still equivalent to my answer. Was I right? Regardless I still don't get the point :(
