there is a base rule for logs ___ Logb(a) = Log(a) / Log(b)

Ln is "natural" log ___ the base is e

Ln(k) = Loge(k) = Log(k) / Log(e)

so you have ___

Lnk*(Log e/Log k)
----
= (ln(k))*(log(e)/log(k))
---
= [log(k)/log(e)] * [(ln(e)/ln(10)] / [ln(k)/ln(10)
-----
= [log(k)/log(e)] * [ln(e)/ln(k)]
---
= [(ln(k)/ln(10))/(ln(e)/ln(10)] * [ln(e)/ln(k)]
---
= [ln(k)]
----
= 1
