Sep 3, 2015 at 20:31 comment added Oleg567 Thank you to everyone for so high vote for this question/answer. But I am confused: last modifications to any answer were made $>12$ hours ago. How do you find this question? Is there some top-list of daily questions/answers? that amount of views is $>1700$ now.
Sep 3, 2015 at 15:33 comment added njuffa That step seems to include division by $1.1^{2}$
Sep 3, 2015 at 15:18 comment added geometrian Umm, how did you go from step 4 to 5? It should be $2^3 1.1^3 \gtrless 3^2 1.1^2 \rightarrow 8 \cdot 1.331 \gtrless 9 \cdot 1.21 \rightarrow 10.648 < 10.89$.
