What must logb 1 be equal to?

3. 9. a) Solve for x: log4 xX = b Write as a single log: 2log, 3x + 3log5y – 4log5z

Solve for x in each of the following. Make sure to check for extraneous solutions! a) What is a ration a) log,(x - 4) = log,(3x - 1) %3D b) For the rationa undefined? b) log;2 + log;(x - 5) = 4 (hint: use product property first) %3D Simplify the follo simplified, say c) log,(x? - 6) = log,(x) %3D エ+10 C) r+5

. This Simplification of the expression below, where u, v, and w denote suitable positive realy numbers and is equal to zero (0). Explain what property makes the situation so.
