Let's solve this,

= √5 . √15

  • "." here means multiply, am sure u know

= √5 × √3 × 5

  • constituent of 15 is 3 × 5

= √5 × 3 × 5

  • "√" can be taken common
  • as there is a pair of 5, which means it is a square we can take it out of the sqaure root.

= 5√3

And our answer is done, option 5√3! :P
