IT WILL BE THE ANSWER

Answer 2

As per the data given in the above question.

In the above question, it is given that,

The given data is (105)²,

We have to evaluate the given equation by identity method.

Thus, identity is comparing one equation with another equation.

$105^{2} =(100+5)^{2}$

Comparing we get,

$\left[(a+b)^{2}=a^{2}+b^{2}-2 a b\right]$

Substitute the value after compare we get,

$\begin{array}{l}=(100)^{2}+(5)^{2}+2(5)(100) \\=10000+25+1000 \\=11025 .\end{array}$

Hence we get 11025.
