Try It 10.65: Expanding a Logarithm Using the Product and Power Properties

Apply the properties of logarithms to expand the expression log⁡2(5x4y2)\log_2(5x^4y^2). First, use the Product Property to rewrite the logarithm of the product as a sum: log⁡25+log⁡2x4+log⁡2y2\log_2 5 + \log_2 x^4 + \log_2 y^2. Then, apply the Power Property to bring the exponents to the front as multipliers: log⁡25+4log⁡2x+2log⁡2y\log_2 5 + 4\log_2 x + 2\log_2 y. Since log⁡25\log_2 5 cannot be simplified further into an integer or simple fraction, the final expanded expression is log⁡25+4log⁡2x+2log⁡2y\log_2 5 + 4\log_2 x + 2\log_2 y.
