if x=square root of 6 and y^2=12 then 4/xy=
y² = 12y = 2√3x = √6Now, 4 /xy= 4/2√3√6= 2 / 3√2= √2/3In short, Your Answer would be √2 / 3Hope this helps!
x = root(6)y = root(12)4/(root(6)root(12)) = 4/root(72) multiply top and bottom by root(72)4root(72)/72 =root(72)/18root(72) = root(6^2 2) = 6root(2)6root(2)/18 = root(2)/3final answer root(2)/3
