if n is a positive integer , is (1/10) ^ n < 0.01?
1) n > 2
2) (1/10)^ (n-1) < 0.1
i can tell that the condition 1 is true, though when simplifying the inequality as presented in 2 , i get n < 2 which makes the original equation false. ( 0.1 ^ (n-1) < 0.1 ^ 1) = (n-1) < 1 = n < 2.
apparently each statement alone is sufficient.
