Chapter 6 - Inverse Functions - 6.3 Logarithmic Functions - 6.3 Exercises: 5

Answer

(a) 4.5 (b) -4

Work Step by Step

(a) Since, $e^{lnx}=x$ Thus, $e^{ln4.5}=4.5$ (b) Use logarithmic base formulas $\log_{b}x=\frac{log x}{log b}$ $\log_{10}0.0001=\frac{log (0.0001)}{log 10}=\frac{log`10^{-4}}{log10}$ Hence, $\log_{10}0.0001=-4$
