Algorithm is described below.
Explanation:
The Change of Base Formula states, that :
So you can change logarythm to any base convinient. Calculators usually have 2 logarythms: decimal (base 10) and natural (base
To calculate it on a calculator you should:
1) Press 3 and "
2) Press "
3) Press
4) Press "/"
5) Press "
