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.

   • 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.
