Chapter 4 - Exponential and Logarithmic Functions - Exercise Set 4.3: 70

Answer

$= \log (\frac{x(x-2)}{15})$

Work Step by Step

$= \log x + \log(x^{2}-4)-\log 15 - \log(x+2)$ $= \log (x(x^{2} -4))-\log 15 - \log(x+2)$ $= \log (\frac{x(x^{2}-4)}{15})- \log(x+2)$ $= \log (\frac{x(x^{2}-4)}{15(x+2)})$ $= \log (\frac{x(x-2)(x+2)}{15(x+2)})$ $= \log (\frac{x(x-2)}{15})$
