Answer:
C
Step-by-step explanation:
First we simplify what we can in the expressions. 3sqrt(3y) can't be so we leave that. We want to try and get everythig to have sqrt(3y) in it though.
sqrt(27y^5) = sqrt((3^3)y^2y^3) = sqrt(3^2y^4*3y) = 3y^2*sqrt(3y)
y^2*sqrt(75y) = y^2*sqrt(5^2*3y) = 5y^2*sqrt(3y)
So now we have 3sqrt(3y) - 3y^2*sqrt(3y) + 5y^2*sqrt(3y)
If we factor out sqrt(3y) we get (3-3y^2+5y^2)sqrt(3y) = (3+2y^2)sqrt(3y) So that's C
Let me know if you don't get how I did something though and I'll be happy to explain it.
