Sure it will be. When will season 2 start?Log in to reply

– Alex Spagnoletti · 9 months, 2 weeks ago

Surely it will be so.Log in to reply

What does Spagnoletti mean when writing "there are only 2 solutions which are s + r = p"? What is s and what is r and what is the equation we are supposed to be solving? (Since the first is assumed correct for all x if I am reading it right) – Alex Li · 9 months, 3 weeks ago

Apparently I am just dumb, because I don't understand the next one either - a^x+b^x=2^y 1^1+3^1=2^2 a≠bLog in to reply

I think that you can start note-2 soon. There are well over 100 comments and it is very hard to see to where someone commented.Log in to reply

I think that it will be better if every person is allowed to post 1 EPP per regular question. – Svatejas Shivakumar · 9 months, 3 weeks ago

okay !Log in to reply

@Svatejas Shivakumar , @Sharky Kesa

I still think that there can be some conclusion for EPP problem 1 . We are getting a number which is divisible by 2000 which has one factor which is given number , ...So there can be some relation ... – Chinmay Sangawadekar · 9 months, 3 weeks ago

With the question, what you actually want to try to prove is that the expression is divisible by 16 and 125.Log in to reply
