The formula y = logb x is said to be written in logarithmic form and x = by is said to be written in exponential form. In working with these problems it is most important to remember that y = logb x and x = by are equivalent statements. Example 1 : If log4 x = 2 then x = 42 x = 16 Example 2 : We have 25 = 52. Then log 5 25 = 2. Example 3 : If ...

† Logarithmic function: Let a be a positive number with a 6= 1. The logarithmic function with base a, denoted loga x, is deflned by y = loga x if and only if x = ay: Important Formulas: † Compound Interest: is calculated by the formula A(t) = P ‡ 1+ r n ·nt where A(t) = amount after t years P = principal r = interest rate n = number of ...
