Answer:

Verify x+(y+z)=(x+y)+z for the following values of

x,y,z (i)x=3/4,y=5/6,z=-7/8(ii)x=2/3,y=-5/6,z=-7/9(iii) x=3/5,y=-6/9,z=2/10(iv)x=-3/5,y=-7/10,z=-8/15

To Verify x+(y+z)=(x+y)+z

(i)x=3/4,y=5/6,z=-7/8

LHS = 3/4 + (5/6 + (-7/8)) = (3/4) + (5/6 -7/8) (3/4) + ((20-21)/24) = 3/4 - 1/24 =

=(18-1)/24 = 17/24

RHS = (3/4 + 5/6) + (-7/8)= (9 + 10)/12 - 7/8 =

19/12 - 7/8 = (38 - 21)/24 = 17/24 LHS = RHS = 17/24

(ii)x=2/3,y=-5/6,z=-7/9

LHS = 2/3 + (-5/6 + (-7/9) = 2/3 + (-5/6 - 7/9) = 2/3 + (-29/18) = 2/3 - 29/18

= 12/18 - 29/18 = -17/18

RHS = (2/3 + (-5/6) ) + (-7/9) = (2/3 - 5/6) - 7/9 = (-1/6) - 7/9 = -1/6 - 7/9 = -3/18 - 14/18 = -17/18

LHS = RHS

Hence verified
