1 LogA is a Log in base 10. Or if it says something like this Log100=2. This means Log in
Base 10 is squared to make 100.
1.1 If the Log has a small number (would show but not supported on this website) after the log then the
log is in that base and not 10.
2 LogY + LogX= LogYX
3 LogY - LogX= LogY/X
4 There are many like the base change
rule but that can't is shown here
because no small number is
supported on this website. However
where possible i have shown the
rules. I cannot however show
worked examples effectively.
