Plz solve all parts..
(d) For which natural numbers n is the following statement true?
(3 X (n³ + 5n)) = (n² is irrational)
Justify your answer.
(e) () Let f(2) = 2021 – N21895 + 1066, where N is your five-digit candidate number. Is it true
that we can write f(2) = II (2 - c), where c € C for each 1sis 2021 ?
(i) Is the following statement true? For each 1<i< 2021, we have c; e R.
You must justify your answer.
