24. (2) ( frac{2^{-3} times 3^{-2} times 2^{6}}{6^{2} times 9 times 3^{-5}} ) ( =frac{2^{-3} times 3^{-2} times 2^{6}}{(2 times 3)^{2} times 3^{2} times 3^{-5}} ) ( =frac{2^{-3} times 3^{-2} times 2^{6}}{2^{2} times 3^{2} times 3^{2} times 3^{-5}} ) ( =frac{2^{-3+6} times 3^{-2}}{2^{2} times 3^{2}+2-5}=frac{2^{3} times 3^{-2}}{2^{2} times 3^{-1}} ) ( =2^{3-2} times 3^{-2}+1 ) ( =2^{1} times 3^{-1}=frac{2}{3} )
