Exponential and logarithmic equations. This is because scientific and graphing calculators are equipped with a button for the common log that reads $log$, and a button for the natural log that reads $ln$ which allows us to obtain a good approximation for the common or natural log of a number. The natural logarithm of zero is undefined: ln(0) is undefined. p&=81 The natural logarithm of x is generally written as ln x, log e x, or sometimes, if the base e is implicit, simply log x. In a sense, logarithms are themselves exponents. log e = ln (natural log). N&=3 Then, the E E E and N N N changes sides so that the E E E now goes on to the right side of the equation in a logarithm, and the N N N goes to the left side. Question 1: Convert .
