Theory of Logarithm
Logarithms to its own base: Logaa = 1
Addition Law: logax + logay = logaxy
Subtraction Law: logax – logay = {\color{Blue} log_{a}\frac{x}{y}}
Power Law: logaXn = nlogaX
Power of the base: loga2 X = ½loga X
Logarithm of 1: loga1 = 0
Reciprocal Law: logaM = {\color{Blue} \frac{1}{log{_{M}}^{a}}}

Change of base: {\color{Blue} \mathbf{{log_{a}}^{M} = \frac{log{_{y}}^{M}}{{log_{y}}^{a}}}}
