Remember that a logarithm is the power to which a number must be raised to obtain another number. For example, the base 10 logarithm of 100 is 2, since 10 raised to the power of 2 equals 100: \log (100)=2 log(100) = 2. because: { {10}^2}=100 102 = 100. The base is the number that is being raised to a power. dr. nancy peters buffalo nyWeb1.5.3: Solving Exponential Statements.
