Given:

L=\lim_{x\rightarrow 0}\dfrac{(x+1)^5-1}{x}

Using binomial expansion expand (x+1)^5

L=\lim_{x\rightarrow 0}\dfrac{x^5+5x^4+10x^3+10x^2+5x+1-1}{x}

L=\lim_{x\rightarrow 0}\dfrac{x^5+5x^4+10x^3+10x^2+5x}{x}

L=\lim_{x\rightarrow 0}\dfrac{x(x^4+5x^3+10x^2+10x+5)}{x}

L=\lim_{x\rightarrow 0}x^4+5x^3+10x^2+10x+5

Apply limit

L=5
