Question

What is the square root of 15 plus the square root of 15?

Answer 1

Answer= `2.sqrt(15)`

Explanation:

Let `C=A+B`

Assume A=B and therefore substitute A instead of B

`""color(white)(a)=>C=A+A`

`""color(white)(a)=>C=2A`

From data given in the question `A=B=sqrt(15)`

Then `C= 2sqrt(15)`
