(B) ધારો કે $y = \mathop {\lim }\limits_{x 	o 4} \left[ {\frac{{{x^{3/2}} - 8}}{{x - 4}}} ight]$.સૂત્ર $\mathop {\lim }\limits_{x 	o a} \frac{{{x^n} - {a^n}}}{{x - a}} = n{a^{n - 1}}$ નો ઉપયોગ કરતા:અહીં $n = 3/2$ અને $a = 4$ છે.$y = \frac{3}{2} 	imes {(4)^{(3/2) - 1}} = \frac{3}{2} 	imes {(4)^{1/2}} = \frac{3}{2} 	imes 2 = 3$.વૈકલ્પિક રીતે,$L$-Hospital ના નિયમનો ઉપયોગ કરતા:$\mathop {\lim }\limits_{x 	o 4} \frac{{\frac{d}{{dx}}({x^{3/2}} - 8)}}{{\frac{d}{{dx}}(x - 4)}} = \mathop {\lim }\limits_{x 	o 4} \frac{{\frac{3}{2}{x^{1/2}}}}{1} = \frac{3}{2} 	imes \sqrt{4} = \frac{3}{2} 	imes 2 = 3$.

$\mathop {\lim }\limits_{x \to 4} \left[ {\frac{{{x^{3/2}} - 8}}{{x - 4}}} \right] = $
