Hello Student,
Please find answer to your question below

I = \lim_{x\rightarrow 0}\frac{\int_{0}^{x^2}sin\sqrt{t}dt}{x^3}
It is 0/0 form. Apply L’hospital rule
I = \lim_{x\rightarrow 0}\frac{sin\sqrt{x^2}.2x}{3x^2}
I = \lim_{x\rightarrow 0}\frac{2sinx}{3x}
I = \frac{2}{3}\lim_{x\rightarrow 0}\frac{sinx}{x}
I = \frac{2}{3}
