If n is any natural number, then 9^(n)-5^(n) ends with

If n is a natural numbers then 25^(2n)-9^(2n) is always divisible by

If n is any natural number then n^(2)(n^(2)-1) is always divisible

If n is an odd natural number 3^(2n)+2^(2n) is always divisible by

For natural number n , 2^n (n-1)!lt n^n , if

If n is any even number, then n(n^(2)+20) is always divisible by

If n is any natural number,then 6^(n)-5^(n) always ends with (a) 1 (b) 3 (c) 5 (d) 7 [Hint: For any n in N,6^(n) and 5^(n) end with 6 and 5 respectively.Therefore,6^(n)-5^(n) always ends with 6-5=1.

If n is a natural number then show that n! + (n+1)! = (n+2)n!
