Hi,

Let X be a locally Euclidean Hausdorff space. Show that if X is compact,

then X is second countable.

The claim can be generalized to if and only if by replacing compact with

sigma-compact, but let's concentrate on this implication. I've managed

to prove X LindelĂ¶f and first-countable, but these seem to be too weak

properties to prove second countability. I'm pretty sure that I should

somehow pull in the second countable basis of R^n by the locally

Euclidean homeomorphisms. Any hints?
