[" 20.If "n" is any natural number then "6^(n)-5^(n)" always end with "],[[" (a) "1," (b) "3," (c) "5]]

If n is a any natural number ,then 6^n-5^n is always end with

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

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

If n is any natural number, then 6^n-5^n always ends with ............................. (a) 1 (b) 3 (c) 5 (d) 7

If n is a natural number, then (4^(n) -3n -1) is always divisible by-

For any 'n', 6^(n) - 5^(n) ends with
