How do you use the Change of Base Formula and a calculator to evaluate the logarithm #log_3 21.8#?
Algorithm is described below.
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 "
4) Press "/"
5) Press "
6) Press "=" to get final result.
Note: I described the algorithm using
