### Re: Minimum value

No.
If, X>0, y>0
Then, it could be x=y=0.1 or 0.01 or 0.000001
Because, x and y are real number.

### Hey! There is a 'JHAMELA'

If, a=b
Then,
a^2=ab
=>a^2-b^2=a^2-ab
=>(a+b)(a-b)=a(a-b)
=>a+b=a
=>a+a=a
=>2a=a
=>2=1
I know there is a mistake in this calculation. What's that and please give me a logic behind that mistake.
