Answer:

$\sum_(n=10)^(15)(n+(3)/(n))=\sum_(n=10)^(15) n + \sum_(n=10)^(15) (3)/(n)$

Explanation:

Given expression :
$\sum_(n=10)^(15)(n+(3)/(n))$

Solving further:

$\sum_(n=10)^(15)(n+(3)/(n))$

$\Rightarrow \sum_(n=10)^(15) n + \sum_(n=10)^(15) (3)/(n)$

So,
$\sum_(n=10)^(15)(n+(3)/(n))=\sum_(n=10)^(15) n + \sum_(n=10)^(15) (3)/(n)$

So, Option A is true

Hence the given expression is equivalent to Option A
