"n" is a + integer not exceeding 9 the list of all "n" such that 10 divides n^n-n is
The value of n must be among those numbers such that the ones digit of n^n be n.Now, ones digit of 3^3 = 9,so, n doesn't equal 3.Now, If n = 1, then, 1^1 = 1 ,so, n can be 1.Similarly, the all values of n among 1 and 9 can be 1,5,6 and 9.
