Answer 1

A) (1/4)^-1 * (1/2)^-2 = 4*4 = 16

B) (2 i 1/2)^-2 * (-1/2)^-3 = (5/2)^-2 * (-1/2)^-3 = 1/(5/2)^2 * 1/(-1/2)^3 = 1/(25/4) * 1/(-1/8) = 1 : 25/4 * 1 : (-1/8) = 1*4/25 * 1*(8/-1) = 4/25 * (-8) = - 32/25

C) (-5/8)^-2 + 1^-1 -3 = 1/(-5/8)^2 + 1/1 - 3 = 1 : 25/64 - 2 = 1*64/25 - 2 = 64/25 - 2 = 14/25

D) (10/11)^-2 + (1 i 3/3)^-2 + 0,08 = (10/11)^-2 + 2^-2 + 0,08 = 1/(10/11)^2 + 1/4 + 0,08 = 1 : 100/121 + 1/4 + 0,08 = 1*121/100 + 1/4 + 0,08 = 121/100 + 1/4 + 0,08 = 121/100 + 25/100 + 8/100 = 154/100 = 77/50 = 1 i 22/50
