Answer 2

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, $(102)^2=10404$
