If the product of `n` positive numbers is `n^n`. Then their sum is

The product of n positive numbers is unity. Then their sum is:

If the product of n positive numbers is 1, then their sum will be

If the product of n positive numbers is 1, then their sum is

The product of n positive numbers is unity, then their sum is (1991,2M) a positive integer (b) divisible by n equal to n+(1)/(n) (d) never less than n

If the sum of n positive number is 2n, then the product of these numbers is (A) le2^n (B) ge2^n (C) divisible by 2^n (D) none of these

If the arithmetic mean of the product of all pairs of positive integers whose sum is n is A_(n) then lim_(n rarr oo)(n^(2))/(A_(n)) equals to

If the sum of first n odd natural numbers is 169, then the sum of all natural numbers less than or equal to n is.

Let S(M) denote the sum of digits of a positive number M.Let N be the smallest positive integer such that S(N)=2018. The value of S(5N+2018) is
