Answer 1

Hello mate...

Answer..

( 102 )²

[using identity] -- ( a + b )² = a² + 2ab + b²

let put the values...

( 100 + 2 )²

= ( 100 )² + 2 × 100 × 2 + ( 2 )²

= 10000 + 400 + 4

= 10404

Answer 2

102² =(100+2)² is of the form,

(a+b)² =a² +b² +2ab

where a=100,b=2

∴102² =(100+2)²

=100² +2² +2×100×2

=10000+4+400=10404
