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!
