Ifa=1/2,b=3/4,verify the following: 1.a*b=b*a 2.a+b=b+a

Answer 1

Step-by-step explanation:

1.a*b=b*a

LHS=a*b

= 1/2*3/4

= 3/8

RHS = 3/4*1/4

=3/8

=LHS

2.a+b=b+a

LHS=a+b

= 1/2+3/4

= 5/4

RHS = 3/4+1/2

= 5/4

= LHS

Answer 2

1)a*b=b*a
=1/2*3/4=3/4*1/2
=3/8=3/8
=L.H.S=R.H.S
2)a+b=b+a
=1/2+3/4=3/4+1/2
=2/4+3/4=3/4+2/4
=5/4=5/4
=L.H.S=R.H.S
