Example 10.34: Expanding a Logarithm with a Radical
To expand a logarithmic expression containing a radical, such as , first rewrite the radical with a rational exponent, resulting in . Next, apply the properties of logarithms systematically. Use the Power Property, , to bring the rational exponent to the front: . Then, apply the Quotient Property to separate the numerator and denominator: . Use the Product Property to expand the terms in the denominator: . Apply the Power Property again inside the parentheses: . Finally, simplify by distributing the negative sign to obtain the fully expanded expression: .
