Given (256/81)^-3/4

         = (81/256)^3/4

         = (81^3/4)/(256^3/4)

         = (3^4)^3/4 / (4^4)^3/4

        = 3^3/4^4

        = 27/64.    ---- (1)



Given  (216/343)^-2/3

          = (343/216)^2/3

          = (7^3)^2/3 / (6^3)^2/3

         = 7^2/6^2

        = 49/36      ------- (2)

Now from (1) and (2)

(256/81)^-3/4 * (216/343)^-2/3 = 27/64 * 49/36

                                                 = 1323/2304

                                                 = 147/256.


Hope this helps!
