# Condensing Logarithmic Expressions In Exercises 39–46, use the properties of logarithms to rewrite the expression as the logarithm of a single quantity. (Assume all variables are positive.) See Example 4. 7   ln ( 5 x + 8 ) − 3 2 ln ( x − 9 )

To determine

To calculate: The reduced form of the expression 7ln(5x+8)32ln(x9) using the properties of logarithms.

Explanation

Given Information:

The provided expression is 7ln(5x+8)32ln(x9).

Formula used:

The property of logarithms for the expression lnxn is lnxn=nlnx where x and y are real numbers greater than 0.

The property of logarithms for the expression ln(xy) is ln(xy)=lnxlny where x and y are real numbers greater than 0.

Calculation:

Consider the provided expression, 7ln(5x+8)32ln(x9)

Apply the property of lnxn in the above expression as,

7ln(5x+8)32ln(x9)=ln(5x+8)7ln(x9)32

Now, apply the property of ln(xy) as,

7ln(5x+8)
