first,
rationlise the x and y as follows-
x=root 3+root 2/root 3-root 2
root 3 + root 2/root 3-root 2*root 3 - root 2/root 3+root 2
so we get
x=5+2 root 6
again,rationlise the y
we will gwt
y=5- 2 root 6
now, a to q
(x+y)^2
so,
(5+root 2+5- root 2)^2[here root 2 cancel root 2]
(10)^2
thus,its answer is 100
