Question

The base of a log can't be zero, can it?

Answer 1

no

Answer 2

Using \[\Large \log_{b}(x)=\frac{\log_{10}(x)}{\log_{10}(b)}\]


If the base were zero, then \[\Large \log_{0}(x)=\frac{\log_{10}(x)}{\log_{10}(0)}\], but you cannot evaluate the log of 0


So the base cannot be zero

Answer 3

Ah, that makes sense. Thank you very much.
