Question

5) If a= 2, b=3,c=4,prove that (a×b)×c=a×(b×c)​

Answer 1

Step-by-step explanation:

(a x b)x c = a x (b x c)

( 2 x 3 ) x 4 = 2 x ( 3 x 4 )

6 x 4 = 2 x 12

24 = 24

Answer 2

Answer:

a=2

b=3

c=4

Step-by-step explanation:

so,

$(a \times b) \times c = a \times (b \times c) \\ (2 \times 3) \times 4 = 2 \times (3 \times 4) \\ 6 \times 4 = 2 \times 12 \\ 24 = 24$

LHS=RHS

Thus proved
