Question is:(adsbygoogle = window.adsbygoogle || []).push({});

Evaluate the following limits

lim x--> 0 4^x - e^2x / 2x

So i take derivatives

but thats where im confused.... Whats the derivate of 4^x... x4^-x???

and is the derivative of -e^2x -2e^x???

So then that leaves me with 4x^-x -2e^x /2which is 0... so do i do derivatives again??? It seems like the x's wont go away????
