please simplify it using an identity please help ​

Answer 1

Given: $(5+3)^2$

We have to simplify the above equation.

As we know that$(a+b)^2=a^2+2ab+b^2$.

By using the above equation, we are solving the above equation.

We are solving in the following way:

We have,

$(5+3)^2$

Solving the above equation by using the above identity:

$=>5^2+2\times5\times3+3^2\\=>25+30+9\\=>64$

Hence, the value of$(5+3)^2$is$64$.

Answer 2

Step-by-step explanation:

Solving the above equation by using the above identity:

$\begin{gathered}= > 5^2+2\times5\times3+3^2\\= > 25+30+9\\= > 64\end{gathered} </p><p>=>5 </p><p>2</p><p> +2×5×3+3 </p><p>2</p><p> </p><p>=>25+30+9</p><p>=>64</p><p>$
