Question

evalute using identities204 multipide by 196​

Answer 1

Answer:

⇒204=200+4

⇒196=200-4

204×196=(200+4)(200-4)

by identity,

→(a+b)(a-b)=a²-b²

we have a=200, b=4

⇒(200+4)(200-4)=(200)²-4²

⇒(200+4)(200-4)=40000-16

⇒(200+4)(200-4)=39984

Answer 2

Answer:

According to me

204 × 196

(200+4)(200-4)

= using Identity ( a+b ) ( a-b ) = a^2 - b^2 we get ,

a = 200

b= 4

200^2 - 4^2

40000 - 16

39984
