Question

Using suitable identity, evaluate (103)²​

Answer 1

Step-by-step explanation:

(103)²= (100+3)²

= (100)²+2.100.3 + 3²

= 10000 + 600 + 9

= 10609

[Using identity (a+b)²= a²+b²+2ab]

Answer 2

Answer:

$103^2=10609$

Step-by-step explanation:

Here, let us use the identity $(a+b)^2=a^2+b^2+2ab$

103=100+3

a=100

b=3

$103^2=100^2+3^2+2(100)(3)$

$103^2=10000+9+600$

       $=10609$
