## Conversion formula
The conversion factor from seconds to weeks is 1.6534391534392E-6, which means that 1 second is equal to 1.6534391534392E-6 weeks:
1 s = 1.6534391534392E-6 wk
To convert 112 seconds into weeks we have to multiply 112 by the conversion factor in order to get the time amount from seconds to weeks... | HuggingFaceTB/finemath | |

Say $F$ is a field of characteristic $p$ and let $f(x) = x^p - a \in F[x]$. Show that $f$ is irreducible over $F$ or $f$ splits in $F$.
Well, my solution would be since $Char F = p$, then $(x - a^{1/p})^p = x^p - a$. Therefore, $f$ splits in $F$. Is that correct?

What are examples of parallelizable manifolds, and why does parallelizable correspond to $TM$ being trivial?
I know a differentiable manifold $M$ of dimension $n$ is parallelizable if there exist (smooth of course) vector fields $\{X_i\}_{j=1}^n$ which are linearly independent in $T_pM$ at each point $p \in M$.

Need to show a = – c and b = – d if x2 – 1 is a factor
consider, x2 – 1 is a factor of ax3 + bx2 + cx + d
then x = + 1, x = – 1
substitute x value in the equation ax3 + bx2 + cx + d

Consider a prime number $$p$$ and a finite p-group $$G$$, i.e. a group of order $$p^n$$ with $$n \ge 1$$.
If $$n=1$$ the group $$G$$ is cyclic hence abelian.
For $$n=2$$, $$G$$ is also abelian. This is a consequence of the fact that the center $$Z(G)$$ of a $$p$$-group is non-trivial. Inde... | HuggingFaceTB/finemath | |
