Question

1. Verify the associative property of multiplication
(a X b) x C = a X (bXc)
(1)a=15,b=8,c=10(2)a=12,b=-5,c=-19​

Answer 1

Answer:

a. ( 15 × 8 ) × 10 × = 15 × ( 8 × 10 )

= 120 × 10 = 15 × 80

= 1200 = 1200

its verify

b. [ 12 × ( -5 ) ] × ( -19 ) = 12 × [ ( -5 ) × ( -19 ) ]

= -60 × ( -19 ) = 12 × 95

= 1140 = 1140

it's verify
