0^0 = (0^1)/(0^1) = 0/0 = (0*1)/0 = 0*(1/0) = 0*infinity = 1 , because 1/0 = infinity!

And hoe is that?

#1
its impossible since D is the mid-point of AB and you said that BD=3.6 and AD=1.8,but they should be equal!

I wonder how is it possible that 1/0 doesnt exist and 0/0 does?

No,no,no!
I am saying that 9,999...(=10*0,999...) has one less decimal than 0.999...
Also (10*0,999...)-(1*0.999...)=(10-1)*0.999...=9*0.999...

## #8 Re: This is Cool » 0.9999....(recurring) = 1? » 2009-01-11 06:32:05

i can still prove that infinite isn't same as infinite+1.

infinite=1*x,
but infinite+1=1*(x+1),
so 0.999... has 1 more decimal than 9.999...=10*0.999...

this is nothing i heard that 1+1=1,but i agree.

I heard that you can prove that one plus one equals one! How?
