You can put this solution on YOUR website!
sqrt 9y^2 + sqrt 54y^2
sqrt%289y%5E2%29%2Bsqrt%2854y%5E2%29
sqrt%289y%5E2%29%2Bsqrt%289y%5E2%29%2Asqrt%286%29
3y%2B3y%2Asqrt%286%29
some books and teachers make you say it like this when they don't specify that the variables can be assumed to be non-negative:
3%2Aabs%28y%29%2B3%2Aabs%28y%29sqrt%286%29
If it said simplify, you're done.
If you're supposed to factor:
3y%281%2Bsqrt%286%29%29
or
3%2Aabs%28y%29%281%2Bsqrt%286%29%29
Happy Calculating!!!!
