Question 201008
<font face="Garamond" size="+2">


Use the fact that


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y = \log_b(x) \ \ \Rightarrow\ \ b^y = x]


to write:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \log_4(3x + 7) = 3 \ \ \Rightarrow\ \ 4^3 = 3x + 7]


Then calculate *[tex \Large 4^3] and solve the resulting linear equation for *[tex \Large x]
