Ans:

If the given function in the limit is of zero by zero form, then we can apply L’Hospital rule which is explain below
$L = \lim_{x\rightarrow a}\frac{f(x)}{g(x)}$
f(a) = 0
g(a) = 0
$L = \lim_{x\rightarrow a}\frac{(f(x)-0)}{(g(x)-0)}$
$L = \lim_{x\rightarrow a}\frac{(f(x)-f(a))}{(g(x)-g(a))}$
$L = \lim_{x\rightarrow a}\frac{\frac{(f(x)-f(a))}{x-a}}{\frac{(g(x)-g(a))}{x-a}}$
$L = \lim_{x\rightarrow a}\frac{f'(x)}{g'(x)}$
Similarly follow for higher derivative.
We keep on differentiating until we get an approriate answer.
