Break down the number in the square root, so make it

5 * square root of 9 * square root of 5

5 * 3 * square root of 5

15 * square root of 5

It's just called a square root problem.

You find the square root and then whatever that is then you multiply it by the number on the outside

Alyssa said it! That's multiplying square by a square root? Idk maybe it has no name
