Answer 2

Answer:

Step-by-step explanation:

Given :

To prove that,

$2\ + \ 2 \ = \ 5$

Solution :

We know that,

⇒ $2+2=4$

By adding & subtracting $\frac{9}{2}$ in RHS,

⇒ $2+2=4-\frac{9}{2}+\frac{9}{2}$

⇒ $2+2=(\sqrt{4-\frac{9}{2}})^2+\frac{9}{2}$

⇒ $2+2=\sqrt{(4)^2 - 2(4)(\frac{9}{2}) + (\frac{9}{2})^2}+\frac{9}{2}$

⇒ $2+2=\sqrt{16 - 36 + (\frac{9}{2})^2}+\frac{9}{2}$

⇒ $2+2=\sqrt{-20 + (\frac{9}{2})^2}+\frac{9}{2}$  the move,.

⇒ $2+2=\sqrt{25 - 45 + (\frac{9}{2})^2}+\frac{9}{2}$

⇒ $2+2=\sqrt{(5)^2 - 2(5)(\frac{9}{2}) + (\frac{9}{2})^2}+\frac{9}{2}$

⇒ $2+2=\sqrt{(5-\frac{9}{2})^2}+\frac{9}{2}$

⇒ $2+2=(5 - \frac{9}{2})+\frac{9}{2}$

⇒ $2+2=5 - \frac{9}{2}+\frac{9}{2}$

⇒ $2+2=5$

Hence, proved
