You can put this solution on YOUR website!
%28%28144a%5E8%29%2F%289y%5E18%29%29%5E%281%2F2%29
multiply the inside exponents, by the outside exponent
^1/2 is the square root, find the square root of the numbers
%28%2812a%5E4%29%2F%283y%5E9%29%29
We can reduce the fraction here to
%28%284a%5E4%29%2F%28y%5E9%29%29
