To simplify this expression, we need to simplify the individual radicals.

Let's simplify


Start with the given expression.


Factor to get


Break up the square root.


Take the square root of 16 to get 4


Take the square root of to get


Take the square root of to get


Rearrange the terms.


So where every variable is positive.


============================================================


Now let's simplify


Start with the given expression.


Factor to get


Break up the square root.


Take the square root of 4 to get 2


Take the square root of to get


So where "x" is positive.



===========================================================


Since and (where every variable is positive), this means that





simplifies to





Multiply 4 and 4xy to get 16xy


Multiply 5y and 2x to get 10xy


Factor out the GCF


Combine like terms


Rearrange the terms



=================================================================


Answer:


So where every variable is positive.
