The logarithm base $~$b$~$ of a number $~$n,$~$ written $~$\\log\_b(n),$~$ is the answer to the question "how many times do you have to multiply 1 by $~$b$~$ to get $~$n$~$?" For example, $~$\\log\_{10}(100)\=2,$~$ and $~$\\log\_{10}(316) \\approx 2.5,$~$ because $~$316 \\approx$~$ $~$10 \\cdot 10 \\cdot \\sqrt{10},$~$ and multiplying by $~$\\sqrt{10}$~$ corresponds to multiplying by 10 "half a time"\.

Having a long redlink which does not point anywhere seems weird? Does the page it should point to now exist?

No (and it won't, until someone starts writing good explanations of radicals). I think it's fine to have redlinks to nowhere, when it's not clear yet which page will explain the concept.
