Best ResponseYou've already chosen the best response.0Does 0.999... = 1? Let the orgy begin.

Best ResponseYou've already chosen the best response.0No, because 0.999 will never exceed by 1 point.

Best ResponseYou've already chosen the best response.0I don't even have a waifu. My question: is onesided infatuation real love?

Best ResponseYou've already chosen the best response.5@skullpatrol .99999999... repeating is the same as 1. Proof: x=.9999999999 10x=9.999999999 10xx=9.999999999.99999999999 9x=9 x=1

Best ResponseYou've already chosen the best response.0Bibby, of course it's real love. Don't you get butterflies in your stomach when your waifu comes to cheer you up? Also, pic related, Mai Waifu is drinking tea. Ayin, nope, your equation is nonsensical.

Best ResponseYou've already chosen the best response.0Your 2nd equation violates the multiplicative property of 0. How can 0 times any number be 1?

Best ResponseYou've already chosen the best response.0Because every number is 0, n must be infinite.

Best ResponseYou've already chosen the best response.0Mata, mata. A x B = C C/A = B C/B = A 10 x 0 = 0 0/10 = 0 0/0 = 10

Best ResponseYou've already chosen the best response.5Incorrect. If you start with A x B = C, you can only say C/A=B if you exclude the possibility that A might be 0. Likewise with C/B=A.

Best ResponseYou've already chosen the best response.0I can replace your 10 with "any number" to get 0/0 = "any number."

Best ResponseYou've already chosen the best response.010 x 0 = 0 or a*0 = 0 0/10 = 0 or 0/a = 0 0/0 = 10 or 0/0 = a where a = any number

Best ResponseYou've already chosen the best response.5How 'bout this: Prove that \[\sum_{n=1}^{\infty} \frac{ 1 }{ k }\]diverges.

Best ResponseYou've already chosen the best response.0@Aylin assuming n=k, http://en.wikipedia.org/wiki/Harmonic_series_(mathematics)#Divergence If n is not equal to k, I give up. The problem is too difficult for me. Maybe some Wiles will come along and write a 300 page proof.

Best ResponseYou've already chosen the best response.0Remove the summation ("simplify"): \[ \large \sum_{n=0}^{k}{2^k} \] Think you're so tough? Simplify: \[ \large \sum_{n=0}^{k}{3^k} \]

Aylin

Best ResponseYou've already chosen the best response.5Er... @muntoo the way you've written them the answers would just be \[k \times 2^{2}\]and\[k \times 3^{k}\]respectively.
