The natural log helps us to compute the time taken for growth and decay. The result can be easily checked by using the rules of a natural logarithm to set the following expression: e^y = x then e^3 = 20. Since e is a constant, its powers can be found easily using a calculator. Third, press 'calculate'. The exponentiation is written as = by . When there are multiple terms in the ln parentheses, it helps to explicitly write e as the base and all other terms as exponents of e. In doing so, we get the form eln (x) = , which aids in the simplification process. Hence, x(0) = 1 cup of coffee, t = 6 hours and x(t) = .
