. Below is one of the classic fallacies. Note that each step is justified. This is the amount of details we would like to see in your proofs. Identify the fallacious step and explain. 5 points STEP 1: Let ab. STEP 2: Multiply both sides by a, we get a2 ab STEP 3: Add a2 to both sides, we get a2 + a2-ab + a2b STEP 4: Collecting like terms, we get 2a2...

I understand how it was simplified to n^(∈/(sqrt(logn))), but
I'm trying to understand how to prove that logn grows faster for
0<∈<1. The derivative seems too complicated to prove this via
Lhopital's Rule, so I tried using WolframAlpha to compare the two
with logn as the numerator:
http://www.wolframalpha.com/input/?i=limit+as+n+approaches+infinity+(logn)%2F(n%5E(0.5%2F(sqrt(logn))))&rawformassumption=%7B%22FunClash%22,+%22log%22%7D+-%3E+%7B%22Log10%22%7D
However, this gives me a result of 0 for any value above 0,
which would mean that n^(∈/(sqrt(logn))) grows at a faster rate,
even when 0<∈<1.
