Question

If a=47 , b=3 , verify that -
(a+b) × (a-b) = (a×a) - (b×b)

Answer 1

Step-by-step explanation:

if a=47 , b=3 ,

so, (47+3) x (47-3)=(47x47) - (3x3)

50x44=2209-9

2200=2200

Answer 2

Answer:

2200 = 2200

Hence verified

Step-by-step explanation:

LHS = (a+b)×(a-b)

=(47+3)×(47-3)

=(50)×(44)

=2200

RHS= (a×a) - (b×b)

= (47 ×47) - (3×3)

= (2209) -(9)

= 2200

Therefore LHS =RHS

Hence verified
