Prove that:
(i) 93/2 -3 x 50 - (1/81)-1/2 =15
(ii) (1/4)-2 -3 x 82/3 x40 +(9/16)-1/2 =16/3
(iii) 21/2 x 31/3 x 41/4/10-1/5 x 53/5 ÷ 34/3 x 5-7/5/ 4-3/5 x 6 = 10
(iv) (0.6)0 - (0.1)-1/(3/8)-1(3/2)3 + (-1/3)-1= -3/2
(v) √1/4 + (0.01)-1/2 - (27)2/3 = 3/2
(vi) 2n + 2 n-1/2n+1 -2n = 2n + 2n x 2-1/2n x 21 - 2n
(vii) (64/125)-2/3 + 1/(256/625)1/4 + (√25/3√64)
(viii) 3-3 x 62 x √98 /52 x 3√1/25 x (15)-4/3 x 31/3
