Question

Prove that : 2+2=5 by short method​

Answer 1

Prove that :- 2 + 2 = 5

Solution:-

L.H.S = 2 + 2

= 4

=> 4 - 9/2 + 9/2

=>√( 4 - 9/2)² + 9/2

=> By using the Formula: (a + b)² = a² + b² + 2ab

=> √(4)² - 2.4 × 9/2 +(9/2)² + 9/2

=> √16 - 36 + (9/2)² + 9/2

=> √-20 + (9/2)² + 9/2

=>√25 - 45 +(9/2)² +9/2

=>√(5)² -2.5×9/2 + (9/2)² +9/2

=> (5 - 9/2)+ 9/2

=> 5 - 9/2 + 9/2

=> 5

Hence L.H.S = R.H.S 2+2 = 5
