Re: Please Post the Problems of 2013
একটা ধনাত্মক পূর্ণসংখ্যাকে ফ্যান্টাবুলাস বলা হবে যদি তার আগে অন্তত একটা ধনাত্মক পূর্ণসংখ্যা ফ্যান্টাবুলাস সংখ্যা থাকে।সর্বমোট কয়টা ফ্যান্টাবুলাস সংখ্যা আছে?

Re: Please Post the Problems of 2013
What sort of problem is this? This is an inconsistent definition! If x, x/2, x/4, x/8, ... etc are fantabulous, then this sequence gives infinitely many such numbers. If there is no such number, then there are 0 such numbers. This shows that the problem is inconsistent.Prosenjit Basak wrote:একটা ধনাত্মক সংখ্যাকে ফ্যান্টাবুলাস বলা হবে যদি তার আগে অন্তত একটা ধনাত্মক ফ্যান্টাবুলাস সংখ্যা থাকে।সর্বমোট কয়টা ফ্যান্টাবুলাস সংখ্যা আছে?

Oho....I made a mistake . Every fantabulous must be an integer.That's the main thing. And once again sorry for the inconsistent definition.nayel wrote:What sort of problem is this?

Re: Please Post the Problems of 2013
oh forgot to tell another thing.Fantabulous is a imaginary kind of number. Don't be confused.It's not a complex
number but a imagination. Fantastic + Fabulous = Fantabulous
number but a imagination. Fantastic + Fabulous = Fantabulous

That is very crucial. In this case it is a very nice problem.Prosenjit Basak wrote:Oho....I made a mistake . Every fantabulous must be an integer.That's the main thing. And once again sorry for the inconsistent definition.
