Hello, I solved this question by using an approach different from OG's answer explanation. My answer was correct though.
Could anybody please check my approach and if I am wrong, pls correct it? Thanks!
Q144: If n is a +ve int, is (1/10)^n 2
(2) (1/10)^(n-1) < 0.1
My solution:
is (1/10)^n < (0.01) ?
is (1/10)^n < (1/10)^2 since 0.01 = (1/10)^2
so the question is now: is n < 2?
By taking (1): SUFF
By taking (2): (1/10)^(n-1) < (0.1) which is equal to (1/10)^1
n-1 < 1 or n < 2 SUFF
Answer is D which is correct.

I don't know why, I tried so many times but could not post it exactly I wanted.
Anyways, please read this Q144: If n is a +ve int, is (1/10)^n <0> 2
as
<0> 2 as (0.01) ?
and option (1) n > 2
