Next students define two new variables x log a and y log b and enter them into lists. Logb mn logb mlogb n logb m n logb m logb n logb m. Evaluate each logarithm using the change of base formula.

The logarithmic power rule can also be used to access exponential terms. Using Properties of Logarithms Use log 53 0683 and log 57 1209 to approximate the following. Properties of Logarithms Date_____ Period____ Expand each logarithm.

Sometimes you need to write an expression as a single logarithm. Example 6 Write 2 log 3 x log 3 y as a single logarithm log 3 x 2 log 3 y Use the Power Rule for Logarithms to move the 2 in 2 log 3 x to the exponent of x log 3 x 2y Use the Product Rule for Logarithms. Along with the product rule and the quotient rule the logarithm power rule can be used for expanding and condensing logarithms.

PROPERTIES OF LOGARITHMIC FUNCTIONS EXPONENTIAL FUNCTIONS An exponential function is a function of the form f xbx where b 0 and x is any real number. The Quotient Rule Let and be positive real numbers with The logarithm of a quotient is the difference of the logarithms. Because of the inverse relationship between exponential and logarithmic functions there are several important properties logarithms have that are analogous to ones held by exponential functions.

Log a x log b x log b a The base that you use doesnt matter only that you use the same base for both the numerator and the denominator. Students will state and apply the properties of logarithms.
