Hey, the solution is that it is true for any value of x. Rate me if I'm correct, if not rate me all the same.

Hey, Nigitha , put x=1. We have 23-[22-1]=8-[3]=5 on the L.H.S and on the R.H.S we have 22+1=5 So,x= -1 is not the only answer. YOU ARE WRONG......!!!!!!!! And Aditya, put x=0 L.H.S. = 22-[2-1]=4-1=3 R.H.S. = 2+1=3 , hence x=0 satisfies the equation. YOU ARE WRONG ADITYA............!!!!!!!!!!!!

I agree with metal. I solved it myself and the answer is indeed ALL REAL VALUES OF X.
|
I like to be myself. |

this is such an easy question..
X E R ... all real values of x.
as when we solve, in the last step we get
2 ^(x+2) = 2 ^ (x+2)

You must surely be kidding if you think that to be in the power. It's quite clear enough, isn't it??? Stop being IDIOTIC[never mind the six lettered word in block letters]
