Question

If a = 3, b = -2, c = -1, verify that:
(1) b x (a + c) = b x a + b x c (ii) b x c x a = a x b x c x c x a x b
(iii) b x c = c x b with explainetion​

Answer 1

Answer:

1) b=-2; a=3;c=-1;

= b× (a+b) = b×a+b×c

= -2×(3+(-2)) = -2×3+-2×2

= -2×(3 - 2) = -6+-2+-2

= -2×(1) =-6-4

= -2 =-2

2) b×c×a=a×b×c

-2×-1×3=3×-2×-1

-2×3 =3×-2

-6. =-6

3)b×c=c×b

-2×-1=-1×-2

-2 =-2

THANK YOU

Answer 2

1. a=3,b=-2,c=-1

= -2(3+-1) = 3× (-2) + (-2)×(-1)

= -2(2) = -6 + 2

= -4 = -4

2. (-2)×(-1)×3=3×(-2)×(-1)×(-1)×3×(-2)

= 6 not equal to36

3.(-2)×(-1)=(-1)×(-2)

=2=2

hence verified.

hope it helps you
