Question

if p=-8/27 q=3/4 r=-12/15 then verify p×(q-r)=p×q-p×r

Answer 1

Hi ,

p = -8/27 , q = 3/4 , r = -12/15

LHS = p ( q - r )

= ( -8/27 ) [ 3/4 - ( -12/15 ) ]

= ( -8/27 ) [ 3/4 + 4/5 ]

= ( -8/27 ) [ ( 15 + 16 )/20 ]

= ( -8/27 ) × ( 31/20 )

= - ( 2 × 31 )/( 27 × 5 )

= - 62/135 ---( 1 )

RHS = pq - pr

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

= -2/9 - ( 32 / 135 )

= ( - 30 - 32 )/ 135

= -62/135 ---( 2 )

LHS = RHS
