IF n is a positive integer, is

(1/10)ⁿ < 0.01?

1) n>2

2) (1/10)^n-1 < 0.1

from 2), we can get n <2, so (1/10)ⁿ > 0.01; however, from 1), we can get (1/10)ⁿ < 0.01. I am confused with this controversial results, I selected A, but the standard answer is D.

Pls be careful:

from 2) , we can get n&gt;2, not n&lt;2!
