Question

Verify that (X+y)+z= x+(y+z) if:

X=14/5, y= -3/6 , z= -2/13​

Answer 1

Note: Commutative Law

☞ x + (y+z) = (x +y)+z

Solution:

Given:

x= 14/5

y= -3/6

z= -2/13

T0 Verify:

( x+y) + z = x+(y+z)

Take LHS Term:

( x+y) + z

(14/5 -3/6) -2/13

(84 - 15/30 ) - 2/13

79/30 - 2/13

967/390

Take RHS term :

x+(y+z)

14/5( -3/6 -2/13)

84 - (15/30 - 2/13)

79/30 - 2/13

967/390

Hence, It's Proved!
