Question

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

Answer 1

a

Explanation:

edg 21 ^u^

Answer 2

`\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
