I asked my German friend if he knew the square root of 81.
He said no .

8.999...

8.999...

Engineers eh?

Or 9

Same thing.

Even happier...

I asked my German friend if he knew the square root of 81.
He said no .

Reminds me of an episode of Hogans Heroes

 

[ChristineM]

Same thing.

Not in the real world. There is 0.0...01 difference.

No, the ellipses mean that the nines continue forever.
8.999... = 9 exactly.
Proof is simple.

This nerdy argument pops up on RF regularly.

Note my reply also had ellipses. It does matter how far you go into infinity there is always a difference between 9 and 8.999..

Sure it's close enough but not precise

A mathematician can show that it is precise.

There is no "how far you go into infinity".
Infinity doesn't stop there...wherever "there" is.
Ask @Polymath257.
He'll tell you.

A scientist can show it isn't

I was being flippant . But there is still a difference of O.O...1 no matter how you fudge it

 

[Subduction Zone]

No, he can't. In the sciences there is always a margin of error with measurements. A scientist could only measure his two events and say that (in this case at least)"that within his margin of error that they were the same.value. He could even tell you what the margin of error he had.

 

[Revoltingest]

No one yet has.
You misunderstand infinity.

Consider....
10 x 0.999.... = 9.999...
10 - 1 = 9

9.999.... - 0.999.... = 9.000...

Wrongo pongo!

No argument against that.

An infinite margin of error would still give 0.0...1

Prove it

Speaking of scientists....
