Basic Rules & Properties
If <latex>y=b^x</latex> then <latex>x=log_by </latex>
Rule 1
<latex>log_b(xy) = lob_b(x) + log_b(y)</latex>
Rule 2
<latex>log_b(\frac{x}{y}) = log_b(x) - log_b(y)</latex>
Rule 3
<latex>log_b(x^n) = nlob_b(x)</latex>
Rule 4
<latex>log_b(1) = 0</latex>
Rule 5
<latex>log_b(b) = 1</latex>
