Log x is often written as ln x , and is called the natural logarithm (note: The logarithm of the product is the sum of the logarithms of the factors. Log 7 x = log y 7(x) log 7(y) (division rule). This is because logarithms and indices are. Expand each expression (use expansion properties to expand as much as possible). Log 3(xy) = log 3(x) + log 3(y) (multiplication rule) b. In other words, logarithms are exponents. Y = logax if and only if x = ay, where a > 0. However, before we can deal with logarithms we need to revise indices.
