Find each of the following, to four decimal places, using a calculator. (1/e^3)^2 log 0.082 In 0

Solution

a) e^3 = 20.08553692

1/e^3 = 1/20.08553692 = 0.04978706837

(1/e^3)^2 = (0.04978706837)^2

= 0.002478752177 = 0.0025

b) log (0.082) = -1.086186148 = -1.0862

c) ln (0) = Not defined , or infinite
