Question

12) Verify associative property of addition (x + y) + z = x + (y + z) for the given values of X = -12, y = -9/11, z = 7/-12

Answer 1

Step-by-step explanation:

given condition (x+y)+z=x+(y+z)

and x= -12, y= -9/11 ,z= 7/-12

L.H.S= (X+Y)+Z

=(-12-9/11)+(-7/12)

SIMILARLY R.H.S = X+(Y+Z)

=-12+(-9/11-7/12)

THEREFORE

L.H.S=R.H.S
