Given | x + y + 4 | + √ [(X-2) & sup2;] = 0, find the square root of x power of Y Tick [~] is the root sign,

Given | x + y + 4 | + √ [(X-2) & sup2;] = 0, find the square root of x power of Y Tick [~] is the root sign,

From the meaning of the question, we can see that | x + y + 4 | ≥ 0, √ [(X-2) 2] ≥ 0, and | x + y + 4 | + √ [(X-2) 2] = 0, obviously | x + y + 4 | = 0, √ [(X-2) 2] = 0
So x = 2, y = - 6;
So the square root of X of Y is ± 6
