Question

Using identities 102*103 find the value

Answer 1

102×103
(100+2)(100+3)

(x+a)(x+b)=x^2+(a+b)x+ab

=100^2+(2+3)100+(2×3)
=10000+500+6
=10506

Answer 2

hey friend your ans is :--


here in this case we have to find the ans by using a proper identity.



so let's start⏬






= 102 × 103
= (100 + 2 ) ( 100 + 3) .

= ( x + a ) ( x + b ).

= x ^2 + ( a + b) x + ab.

on putting the value :--

= 100 ^2 + ( 2 + 3 )× 100 +( 2 × 3 )

= 10000 + 500 + 6


= 10506 .


i hope u would like this ans.
