Question

Evaluate by using identity : 102x196.​

Answer 1

Answer:

102x196= 203592

Answer 2

Answer:

Let 102 be written as ( 100 + 2 )

⇒ 102 × 196 ⇒ ( 100 + 2 ) × 196 ⇔ 196 × ( 100 + 2 )

• Using distributive property of addition [ a ( b + c ) = a × b + a × c ]

⇒ 196 × ( 100 + 2 )

⇒ ( 196 × 100 ) + ( 196 × 2 )

⇒ 19600 + 392

⇒ 19,992

Answer is 19992
