Differentiate exe^xex.
A
3(ln7)73x3(\ln 7)7^{3x}3(ln7)73x
B
For constants CCC and kkk,
ddx(Cekx)=\strongCkekx. \frac{\mathrm{d}}{\mathrm{d}x}\left(Ce^{kx}\right)=\strong{\boxed{Cke^{kx}}}. dxd(Cekx)=\strongCkekx.C
exe^xex
D
When differentiating ekxe^{kx}ekx, the power rule does not apply, so the exponential expression stays unchanged.
