@Chinmay Sangawadekar Sure it will be. When will season 2 start?

@Chinmay Sangawadekar Surely it will be so.

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)

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≠b

Yes probably it is positive integers other than 1. @Sharky Kesa please reply and change the problem title to EPP set 3 #1

I will ask this question to him in the main note itself as I am not able to tag him.

Guys I will be inactive on Brilliant for 6-7 days as I am going on holiday trip....:( :( :( :(

Chinmay Sangawadekar - 1 year, 8 months ago

After shivam jadhav's problem is solved , I think we must move on to new fresh , note ....

Till Shivam's problem unsolved you can post extra participation problems ......... anybody who wants to ....but only 1 EPP is allowed . per regular question.

Keep this in Mind !!!!

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.

Brilliant Member - 1 year, 7 months ago

I think we will start the new note after say problem 15 as the contest started just few days back and it will be difficult for some people to start from the second note. The note can be made better if we all delete all the unnecessary comments.

I think that it will be better if every person is allowed to post 1 EPP per regular question.

okay !

@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 ...

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