This becomes even more important when dealing with log equations since they have restricted domains. Ex8) log (5x) + log (x – 1) = 2 Ex9) ln (3x – 2) + ln (x – 1) = 2 ln x. Ex10) log4(3x – 8) = 3 Ex11) ln(5x – 1) = ln(x +2) + ln2. Ex12) 36 x + 2 = 6 x – 1 Ex13) 3x + 3 = 2x ONE-TO-ONE PROPERTIES: For any exponential function f (x ...

Understand definition of logarithm in base 10 and be able to convert between exponential and logarithmic equations. Be able to solve simple log equations in one variable (4.7). Note: Some instructors choose to wait and teach 4.7 (intro to logs) in conjunction with chapter 6. The Laws of Exponents and an Introduction to Logarithms
