Question

verify the property a×b=b×a if a = -1/3,b=2/7​

Answer 1

Answer:

Step-by-step explanation:

-1/3×2/7= -2/21

2/7×-1/3= -2/21

Hence,a×b = b×a

Answer 2

Answer:

Step-by-step explanation:

To verify- a*b=b*a

Given- a= -1/3, b= 2/7

Proof-

L.H.S:  a*b -----i

          putting the value of a and b in the equation i

        So, -1/3*2/7

              -2/21

R.H.S:   b*a -----ii

           putting he value of b and a in equation ii

          So, 2/7*-1/3

                -2/21

          L.H.S=R.H.S
