Please, eight times ten to the power of 67 equals? I have read that this is the number of combinations that a pack of cards can be shuffled into. Is this equation correct? I would have thought this would have been 52×52×52? Clearly my math skills are lacking, please help. Thanks. Anton 81.131.40.58 ( talk) 09:12, 24 January 2020 (UTC)
I have replaced letter x with a multiplication symbol × in maths above. -- CiaPan ( talk) 10:08, 24 January 2020 (UTC)
So that's 80,000, 000,000,000, 000,000,000, 000,000,000, 000,000,000, 000,000,000, 000,000,000, 000,000,000? Thanks. Anton 81.131.40.58 ( talk) 11:44, 24 January 2020 (UTC)
Does the sequence a(n) = a(n-1) + 1/n have a limit?
Thanks, BobsFullBogs ( talk) 16:58, 24 January 2020 (UTC)
Is there a recognised function defined as the product of all primes up to and including a given prime?
Ex: F(13) = 2 x 3 x 5 x 7 x 11 x 13 = 30030.
