2+2=4
 it can be written as 4-(9/2)+9/2
                            = √(4-9/2)² + 9/2
                            = √16-2×4×(9/2)²  +9/2
                            = √-20+(9/2)² +9/2
                            = √25-45+(9/2)² +9/2
                            = √5²-2×5×9/2 +(9/2)²
                           = √(5-9/2)² +9/2
                            = 5+9/2-9/2
                            = 5
Hence it is proved.

plz mark it as best and click at thanks
hope it helps u
welcome
√(4-9/2)² from this u didnt get √16-2×4×(9/2)²

As 4-4 =10-10

2^2-2^2=2*5-2*5

(2-2)*(2+2)=5*(2-2)

simplifying both sides with (2-2) 
ans becomes  2+2=5                                                            
 
 










note:--this is practically we cant do as w e  cant cancel (2-2) as it becomes zero 
due to this one of the ans can be cancel
