Let `N=55^3+17^3-72^3dot` Then, N is divisible by both 7 and 13 (b) both 3 and 13 both 17 and 7 (d) both 3 and 17

Let N=55^(3)+17^(3)-72^(3). Then,N is divisible by both 7 and 13 (b) both 3 and 13 both 17 and 7(d) both 3 and 17

N = 55^3 + 17^3 - 72^3 , then N is divisible by :

Show that (17^(3)+7^(3)) is divisible by 24.

10^(n) +3(4^(n+2) )+5 is divisible by (n in N): a)7 b)5 c)9 d)17

If n is a natural number, then 9^(2n)-4^(2n) is always divisible by (a) 5 (b) 13 (c) both 5 and 13 (d) none of these

If -3x+17 lt -13 , then

If -3x+17 lt -13 , then

7.5^(2n-1) + 2^(3n+1) is divisible by 17 for every natural n ge 1 .

If n is a natural number,then 9^(2n)-4^(2n) is always divisible by 5 (b) 13 (c) both 5 and 13 (d) none of these
