\bf We\:\: Have

\rm\to \dfrac{d(x^3+2x^2+5x+100)}{dx}

\bf For\:Differentiation\:we\:use\:this\;Rule

\rm\to\dfrac{d(x^n)}{dx} =nx^{n-1}

\bf We\:\: Write \:\: as

\rm\to \dfrac{d(x^3)}{dx} +2\dfrac{d(x^2)}{dx} +5\dfrac{d(x)}{dx} +\dfrac{d(100)}{dx}

\rm\to 3x^{3-1} + 2\times2x^{2-1}+5 \times 1 + 0

\rm\to 3x^2+4x+5

\bf Answer

\rm\to 3x^2+4x+5

\bf MORE\:\: INFORMATION

\rm\to\dfrac{d}{dx}(x)=1

\rm\to\dfrac{d}{dx}(ax)=a

\rm\to\dfrac{d}{dx}(Cosx)=-Sinx

\rm\to\dfrac{d}{dx}(Sinx)=Cosx

\rm\to\dfrac{d}{dx}(tanx)=Sec^2x

\rm\to\dfrac{d}{dx}(secx)=Secxtanx

\rm\to\dfrac{d}{dx}(lnx)= \dfrac{1}{x}
