Expand (i) ((2x)/3-(3)/(2x))^(6) , (ii) ...

Expand (i) `((2x)/3-(3)/(2x))^(6)` , (ii) `(2/x-x/2)^(5)`

Text Solution

Verified by Experts

The correct Answer is:
(i) `(64)/(729)x^(6)-(32)/(27)x^(4)+(20)/(3)x^(2)-20+(135)/(4x^(2))-(243)/(8x^(4))+(729)/(64x^(6))`
(ii) `(32)/(x^(5))-(40)/(x^(3))+(20)/(x)-5x+(5)/(8)x^(3)-(x^(5))/(32)`
