Answer 1

Hey!! _______€^^^___


Mate ____€_______

Her is the ans ____€____

Solution :-

Lets start by pairing

1^2019 and 2018^2019,

2^2019 and 2017^2019 and so on..

We will realise that 1^odd =1 and (-1)^odd = -1 will cancel out.

As 2019 is odd number, all these pairs would give same numbers with + and - sign and cancel out.

Only 2019^2019 and 2020^2019 remain whose remainder would be 0 and 1 respectively.

Hence the answer would be 1
