Question

For the following values of a, b and c, verify that (a x b) x c = a x ( b x c). a.) a. = 1upon 3, b. =-3 upon 4, c. = - 8 upon 9​

Answer 1

Step-by-step explanation:

1.(a×b)×c

=[1/3×(-3/4)]×(-8/9)

=(-1/4)×(-8/9)

=8/36

=2/9

2.a×(b×c)

=1/3×[(-3/4)×(-8/9)]

=1/3×(24/36)

=1/3×2/3

=2/9

Hence,

2/9=2/9

Therefore,

(a×b)×c=a×(b×c)
