Question

evalute (102)2 by using suitable idenity​

Answer 1

Step-by-step explanation:

${102}^{2}$

$= {(100 + 2)}^{2}$

By the identity (a + b)² = a² + b² + 2ab

$= {(100)}^{2} + {(2)}^{2} + 2(100)(2)$

$= 10000 + 4 + 400$

$= 10404$

(100 +2)²

Step-by-step explanation:

using( a+b)² formulae

100²+2×100×2 +2²

10000+400+4

10404
