Logarithms
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.
5 This is the base chnage rule
6 This is called the power rule.
