Answer 2

Answer:

a) Ans- 2860

b) Ans- 11124

Step-by-step explanation:

a) 55 x 52

= (x + a) (x + b)

= (50 + 5) (50 + 2)

= (50)² + (5 + 2) x 50 + 5 x 2

= 2500 + 350 + 10

= 2850 + 10

= 2860

b) 103 x 108

= (x + a) (x + b)

= (100 + 3) (100 + 8)

= (100)² + (3 + 8) x 100 + 3 x 8

= 10000 + 1100 + 24

= 11100 + 24

= 11124
