Question

Use identities to find the square of 103

Answer 1

Heya user
Here is your answer !!

_________

We know that , ( a + b )² = a² + 2ab + b² .

We can use his identity to find the square of 103 .

( 103 )²
= ( 100 + 3 )²
= ( 100 )² + 2 * 100 * 3 + ( 3 )²
= 10000 + 600 + 9
= 10609 . [ Answer ] .

Hope it helps !!

Answer 2

$solution$

(103²= (100 + 3 )²

{Using Identity}

= 100² + 2 × 100 × 3 + 3²

=10000 + 600 +9 =10609

We may also directly multiply 103 by 103 and get the answer.

We will find in this case, the method of using identities even more attractive than the direct multiplication method.1013.
