 Feb 9 asked $G$ is a finite group and $G_1$,$G_2$ are subgroup that $G_1 \cap G_2=\{1\}$, then $|G_1|.|G_2| \big| |G|$? Jan 24 awarded Supporter Jan 24 answered Consider a function $f(x) = x^4+x^3+x^2+x+1$, where x is an integer, $x\gt 1$. What will be the remainder when $f(x^5)$ is divided by $f(x)$?

(=3/sqrt{n})? Jan 24 answered Prove $n^\frac{1+2}{\sqrt{\log n}} = O(n \log n)$ Jan 24 comment Prove $n^\frac{1+2}{\sqrt{\log n}} = O(n \log n)$ do you mean n^{1+2/sqrt{logn}} ? Jan 23 comment Is there any manifold that is not a subspace of a finite dimensional euclidean space? I'm not sure, but someone says that it's a special case, when the space is 'riemannian'..
