Question

For the following values of a, b, and c verify that (a*b)*c = a*(b*c)
a. A = 1/3 B = --3/4 C = --8/9
b. A = 3/5 B = --1/7 C = 1/5

Answer 1

A is the correct option..

step by step explanation :

a) (1/3 * -3/4)* -8/9 = -3/12 * -8/9 = 24/108= 2/9

1/3 * (-3/4 * -8/9) = 1/3 * 24/36 = 1/3 * 2/3= 2/9

so it is the right option ..

b) (3/5 * -1/7)* 1/5 = -3/35 * 1/5 = 3/175

3/5 * (-1/7 * 1/5)= 3/5 * -1/35= -3/175

3/175 is not equal to -3/175 so, this is not the right option
