Find the value of `2log2/5 +3 log25/8 -log 625/128`

Text Solution

AI Generated Solution

To solve the expression \(2\log\frac{2}{5} + 3\log\frac{25}{8} - \log\frac{625}{128}\), we will use properties of logarithms. Let's break it down step by step. ### Step 1: Apply the Power Rule of Logarithms Using the property \(m \cdot \log_b(a) = \log_b(a^m)\), we can rewrite the expression: \[ 2\log\frac{2}{5} = \log\left(\frac{2}{5}\right)^2 = \log\frac{4}{25} \] ...
