# Math Help - a sum problem

1. ## a sum problem

I encounter a problem and i try to solve it for hours, still i could not solve it.

$

\sum_{k=1}^n \log^s{k}
$

what is the result? I really need help.

$sum_{k=1}^{n} lg^{s}k$

What does $sum_{k=1}^{n} lg^{s}k$ mean?
Can't help if we don't what things mean.

Sorry, My latex is weak. the formula should be,

$\Sigma_{k=1}^{n} lg^{s}k$ (s is a constant and s>0)

Is this is what you intended?

$\sigma_{k=1}^{n} lg^{s}k$

or this?

$g^sl \sum_{k=1}^{n}k$

.

$\sum_{k=1}^n \log_s{k}$ ... maybe?

$\log_s{1}+\log_s{2}+\log_s{3}+ ... + \log_s{n} = \log_s(n!)$
