Kudos for a correct solution.
(1) n > −10

Kudos for a correct solution.
Is (0.1)^n > (10)^n --->\(10^{-n} > 10^n\) --->\(10^{2n} < 1\) --->\(10^{2n} < 10^0\) ---> 2n < 0 ---> is n<0?
Per statement 1, n>-10, yes for n=-5 but no for n=5. Not sufficient.
Per statement 2, n<10, yes for n=-5 but no for n=5. Not sufficient.
Combining, the above 2 cases still apply giving you an ambiguous answer.
Thus, E is the
