Properties of Logarithmic and Exponential Functions
For b > 0 and b 1,
if and only if x = y.
If x > 0 and y > 0, then logb x = logb y if and only if x = y. Type I Exponential Equations
Solved in Section 5.2
Easily written as powers of same base
i.e. 125x = 5x
Type 2 Exponential Equations
Cannot be easily written as powers of same base
i.e 7x = 12
General strategy: take the logarithm of both sides and apply the power rule to eliminate variable exponents.
