Question

Which expression is equivalent to 15 (n+3/n) ? £ N=10

Answer 1

Answer:

$\sum_{n=10}^{15}(n+\frac{3}{n})=\sum_{n=10}^{15} n + \sum_{n=10}^{15} \frac{3}{n}$

Step-by-step explanation:

Given expression : $\sum_{n=10}^{15}(n+\frac{3}{n})$

Solving further:

$\sum_{n=10}^{15}(n+\frac{3}{n})$

$\Rightarrow \sum_{n=10}^{15} n + \sum_{n=10}^{15} \frac{3}{n}$

So,$\sum_{n=10}^{15}(n+\frac{3}{n})=\sum_{n=10}^{15} n + \sum_{n=10}^{15} \frac{3}{n}$

So, Option A is true

Hence the given expression is equivalent to Option A
