Vedclass · Answer

(D) हम निश्चित समाकल की परिभाषा का उपयोग करते हैं: $\mathop {\lim }\limits_{n 	o \infty } \frac{1}{n} \sum_{r=1}^{n} f\left(\frac{r}{n}ight) = \int_0^1 f(x) dx$. प्रथम पद के लिए: $\mathop {\lim }\limits_{n 	o \infty } \frac{\sum_{r=1}^{n} r^4}{n^5} = \mathop {\lim }\limits_{n 	o \infty } \frac{1}{n} \sum_{r=1}^{n} \left(\frac{r}{n}ight)^4 = \int_0^1 x^4 dx = \left[ \frac{x^5}{5} ight]_0^1 = \frac{1}{5}$. द्वितीय पद के लिए: $\mathop {\lim }\limits_{n 	o \infty } \frac{\sum_{r=1}^{n} r^3}{n^5} = \mathop {\lim }\limits_{n 	o \infty } \frac{1}{n^2} \left( \frac{1}{n} \sum_{r=1}^{n} \left(\frac{r}{n}ight)^3 ight) = 0 	imes \int_0^1 x^3 dx = 0 	imes \frac{1}{4} = 0$. अतः,परिणाम $\frac{1}{5} - 0 = \frac{1}{5}$ है।

$\mathop {\lim }\limits_{n \to \infty } \frac{{1 + {2^4} + {3^4} + .... + {n^4}}}{{{n^5}}} - \mathop {\lim }\limits_{n \to \infty } \frac{{1 + {2^3} + {3^3} + .... + {n^3}}}{{{n^5}}} = $
