What is the answer for Two y square root 2( x +y) when x=1 and y =4
1 answer:
Given expression is 2 y √ ( 2 (x + y ) .
Here x = 1 and y = 4 .
We have 2 ( x + y ) in square root in the given expression .
To find the answer of the given expression , we need to plug the given values
of x and y .
We plug " 1 " in place of x and " 4 " in place of y .
Then we need to simplify the given expression .
Please see the attachment .
On simplifying we get 8 multiply square root 10 .
Value of square root 10 is 3.1623 .
Thus the value of the expression is 8 * √10 = 8 * 3.1623
= 25.2982 .
