Question

Evaluate 123whole square use identity

Answer 1

Answer:

(102)^2=10404

Step-by-step explanation:

Given : Number (102)^2.

To find : Evaluate the number whole square using identity?

Solution :

We can write the number

(102)^2=(100+2)^2

Using identity, (a+b)^2=a^2+2ab+b^2

Substitute a=100 and b=2

(100+2)^2=100^2+2(100)(2)+2^2

(100+2)^2=10000+400+4

(100+2)^2=10404

Therefore, (102)^2=10404
