1 = (1 x 3)/3

1 = (0.333333333....33) x 3

1 = 0.99999..999

=> 0.0000....001 = 0

=> 1/10^ ∞ = 0

=> 1 = 0

1 = (0.333333333....33) x 3

1 = 0.99999..999

=> 0.0000....001 = 0

=> 1/10^ ∞ = 0

=> 1 = 0

TopNewestFirst off, \(0 \times \infty\) isn't defined. For more info, refer to indeterminate forms.

Secondly, the last equation should be \[ \lim_{n \to \infty} \frac{1}{10^n} = 0 \]

Rather than \[ \frac{1}{10^{\infty}} = 0 \]

Also, note that \[ \lim_{n \to \infty} 0 \times 10^n = 0 \]

But, \[\lim_{n \to \infty} \frac{1}{10^n} = 0 \not \Rightarrow \lim_{n \to \infty} 0 \times 10^n = 1\] – Deeparaj Bhat · 1 year, 1 month ago

1/10^ ∞ is not exactly equal to 0 its value is too small and greater than 0 so when i multiply it with 0 it should be 0 . And according to your 1st statement 1 is undefinedLog in to reply

\(\dfrac{1}{10^{\infty}}\) isn't even a number!Log in to reply

moreover the main problem is with 3rd step where i am getting 1 is exactly equal to 0.999999..9999 – Ksg Sarma · 1 year, 1 month ago

First errorThe \(.33333....333\) you wrote implies that the \(3\)s will end since the last 3 isn't followed by \(...\) to imply that it repeats infinitely

Second errorThis follows from your first and is very similar.Again.you're implying that the \(9\)s will end sometime,which they don't because the 9s repeat infinitely.(occurs in line 3)

Third errorThis doesn't even make sense.If something equals something,subtracting them from each other will result in exactly \(0\).This follows from your other errors too.(occurs in line 4)

Fourth errorYou can't put \(.000..1\) equal to \(\frac{1}{10^{\infty}}\) because you can't do arithmetic with infinity,it's a concept not a number.

Fifth errorLet's assume you used the correct way to express it which is \[\lim _{n \rightarrow \infty}{\frac{1}{10^{n}}}=0\],you can't multiply each side by \(10^n\) since it's in the limit,and it's not a constant. – Hummus A · 1 year, 1 month ago

in the 1st error you said , tell me how many no. of 3's are there in the middle then I agree that it will end and all the errors are similarLog in to reply

the 3s don't end,they repeat infinitelyLog in to reply

\(0.999\ldots = 1\) exactly!Log in to reply

You can't play with infinity digit number like that! – Darmawan Putra Wijaya · 1 year, 1 month ago
