5xsqrt(3y

Explanation:

1.The first thing you can do is to square x^2. This is easy, you just take away the number 2 and then place x in front of the squareroot. Like this: xsqrt(75y
2. You have to find another way to write 75. You can write 75 like 3*25. But 25 can you also write as 5^2. Then we get
xsqrt(3*5^2y
3. Again square 5^2 by just taking away the number 2. Then you can place the number 5 in front of the squareroot and we get

5x sqrt(3y) and we can't simplify it more
