\(\displaystyle x^3-5x^2+4x-e^x\) where $x$ on e is actualy $x^0$,but i dont know how to write it here.....

i know how to derivate other terms,just this e is suspicious,because its a complement of the function if i am right.....

Another derivate i have to calculate is:

\(\displaystyle ln(x+\sqrt{1+x^{-25}}\)

Thank you all for the help!
