## Logarithms and ratios.This is the question:${\mathrm{log}}_{b}64=\frac{3}{b}$And have to find b.So I tried a bit and got this:$\frac{b}{\mathrm{log}b}=\frac{\mathrm{log}64}{3}$But have no idea what to do next.Thanks for your help.

## When reading about the history of Euclid's Elements, one finds a pretty length story about the Greeks and Arabs spending countless hours trying to prove Euclid's 5th Postulate.But I've yet to come across a source stating that "this is the man who finally proved the 5th postulate!"Has it ever been formally proven, or am I misunderstanding the issue?

## The necessary and sufficient condition for a non - empty subset W of a vector space V(F) to be a subspace of V isa,b in F and $\alpha$, $\beta$ in W implies a$\alpha$ + b$\beta$ in WI need to prove the postulates of vector space with this condition. Hints ?

## My graph theory book postulates the if a simple graph with n vertices has at least C(n - 1, 2) + 2 edges then the graph must be Hamiltonian.This is probably true but I am confused by the notation of what C(n - 1, 2) means?C usually represents a cycle but clearly not in this case. And whatever function they are referencing takes 2 parameters which is quite strange.

## Bertrand's postulate says:For every $n>1$ there is always at least one prime $p$ such that $n.Is the following statement:For every $n>3$ there is always at least one prime $p$ such that ${F}_{n} (${F}_{n}$ is $n$-th Fibonacci number).also valid?If it is invalid, is there a finite or infinite number of ns such that there is no prime between ${F}_{n}$ and ${F}_{n+1}$?This question is inspiblack by another question. I feel intuitively that it may be interesting, but don't have enough number theory background to tackle it.

## Is there a smallest real number $a$ such that there exist a natural number $N$ so that:$n>N\phantom{\rule{thickmathspace}{0ex}}⟹\phantom{\rule{thickmathspace}{0ex}}{p}_{n+1}\le a\cdot {p}_{n}$?I believe it can be proved that $n>7\phantom{\rule{thickmathspace}{0ex}}⟹\phantom{\rule{thickmathspace}{0ex}}{p}_{n+1}\le \sqrt{2}\cdot {p}_{n}$.
