Logarithms

LogV = U is equal to 10^u = V

Properties of Logarithms:
1. LogV and LnV are defined only when V > 0
2. Log1 = 0 and Ln1 = 0
3. Log10^k = K-for every real number K and Lne^k = K-for every real number K
4. 10Log^v = V and eLn^v = V-for every V > 0

Laws of Logarithms: For all v, w > 0
Product law --> Log(VW) = LogV + LogW
Quotient law --> Log(V/W) = LogV - LogW
Power law --> LogV^k = k LogV
