Question

Verify x=3/4, y=5/6, z= -7/8​

Answer 1

Answer:

Concept:

Find:

We have verify that x+(y+z) = (x+y) +z

Given:

We given x=3/4, y=5/6, z= -7/8

Step-by-step explanation:

Now we verify

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

Put x=3/4, y=5/6, z= -7/8

LHS

x+(y+z)

3/4 + (5/6-7/8)

3/4 + (20-21/24)

3/4-1/24

18-1/24

17/24

RHS

(x+y) +z

(3/4+5/6) -7/8

(9+10/12) -7/8

19/12-7/8

38-21/24

17/24

LHS=RHS

Hence we prove LHS=RHS
