Step-by-step explanation:

204×206=42024

Step-by-step explanation:

GIVEN : EXPRESSION 204\times 206204×206

To find : Evaluate the following by using suitable identities ?

Expression 204\times 206204×206 is WRITTEN as,

204\times 206=(200+4)\times (200+6)204×206=(200+4)×(200+6)

Using identity, a(b+c)=ab+aca(b+c)=ab+ac

204\times 206=200(200+6)+4(200+6)204×206=200(200+6)+4(200+6)

204\times 206=40000+1200+800+24204×206=40000+1200+800+24

204\times 206=42024204×206=42024

Therefore, 204\times 206=42024204×206=42024
