Solution
The function e2x is the composition f(g(x)) of two functions f(u)=eu and g(x)=2x.
Apply the chain rule dxd(f(g(x)))=dud(f(u))dxd(g(x)):
(dxd(e2x))=(dud(eu)dxd(2x))The derivative of the exponential is dud(eu)=eu:
(dud(eu))dxd(2x)=(eu)dxd(2x)Return to the old variable:
e(u)dxd(2x)=e(2x)dxd(2x)Apply the constant multiple rule dxd(cf(x))=cdxd(f(x)) with c=21 and f(x)=x:
e2x(dxd(2x))=e2x(2dxd(x))Apply the power rule dxd(xn)=nxn−1 with n=1, in other words, dxd(x)=1:
2e2x(dxd(x))=2e2x(1)Thus, dxd(e2x)=2e2x.
Answer
dxd(e2x)=2e2xA
