Question

for a=2/3 b=4/5 c=-5/6, verify that , (ii) (ab)c =a(bc)

Answer 1

Hi ,

It is given that ,

a = 2/3 , b = 4/5 , c = - 5/6 

LHS = ( ab )c

         = ( 2/3 × 4/5 ) × ( - 5/6 )

         = 8/15 × ( - 5/6 )

         = - 4/9 

RHS = a ( bc ) 

        = ( 2/3 ) × [  4/5 × ( - 5/6 ) ]

         = ( 2/3 ) × ( - 2/3 )

         = - 4/9 


LHS = RHS
