Question

if p = -8/27 , q = 3/4 and r = -12/15 , them verify that : p x (q x r) = ( p x q) x r ​

Answer 1

Step-by-step explanation:

p * (q * r) = ( p * q) * r

L.H.S = p * (q * r)

= -8/27 * (3/4 * -12/15)

= -8/27 * ( -3/5)

= 8/45

R.H.S = (p * q) * r

= (-8/27 * 3/4) * -12/15

= (-2/9) * -12/15

= 8/45

Hence, verify L.H.S = R.H.S
