1) ab = 5*0,4 = 2
ab-1/ab+1 = 2 - 1/2 + 1 = 3 - 1/2 = 2.5
(ab-1)/(ab+1) = (2-1)/(2+1) = 1/3
ab-1/ab+1 = 2 - 1/2 + 1 = 3 - 1/2 = 2.5
(ab-1)/(ab+1) = (2-1)/(2+1) = 1/3
Ab=5*0,4=2
Ab-1/ab+1= 2-1/2+ 1=3-1/2=2,5
(Ab-1):(ab+1)=(2-1)/(2+1) = 1/3
Ab-1/ab+1= 2-1/2+ 1=3-1/2=2,5
(Ab-1):(ab+1)=(2-1)/(2+1) = 1/3
