✺ANSWER.




IQ QUESTION




We all know 2+2=4



But I proved it that how 2+2=5




✦LET'S START☞


TAKE ✍


20-20=25-25


=> (5×4)-(5×4)=(5×5)-(5×5)



=>4(5-5)=5(5-5)


cancel the term (5-5) both side


=> 4=5.

=>2+2=5








✦Prove 2


we know 2+2=4


so add same thing and subtract same have nothing effect on it


$2 + 2 = 4 - \frac{9}{2} + \frac{9}{2}$


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



$formula \: use \ = {(a - b)}^{2} = {a}^{2} + {b}^{2} - 2ab$



$= > \sqrt{16 - (2 )\times( 4) \times (\frac{9}{2}) + { (\frac{9}{2} )}^{2} } + \frac{9}{2}$





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





$= \sqrt{ (- 20) + { \frac{9}{2} }^{2} } + \frac{9}{2}$





$\sqrt{( - 20) - 45 \times {( \frac{9}{2}) }^{2} } + \frac{9}{2}$






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





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




$= > (5 - \frac{9}{2} ) + \frac{9}{2}$




$= > 5$


hence

4=5

=>2+2=5







✦Prove 3




Let

a=b


so,


a×a=a×b


$= > {a}^{2} =a b$




subtract b square both side we get



${a}^{2} - {b}^{2} = a \times b - {b}^{2}$



,
$= > (a + b)(a - b) = b(a - b)$


cancel out (a-b). both side




$= > (a + b) = b$



so, mean


$2b = b \: \: \: \: because \: a = b$


$= > 2 = 1$

1=2




adding 3 both side


$1 + 3 = 2 + 3$






$= > 4 = 5$




$= > 2 + 2 = 5$
