Condense:  log⁡(5x+2) − log⁡3 − log⁡x\log\left(5x+2\right)\ -\ \log3\ -\ \log x  Rewrite:  log⁡ (5x + 2) − (log⁡ 3 + log⁡x)\log\ \left(5x\ +\ 2\right)\ -\ \left(\log_{\ }3\ +\ \log x\right)  Use product and quotient rules

 log⁡(5x+2) ÷log⁡( 3x)\log\left(5x+2\right)\ \div\log\left(\ 3x\right)  

 log⁡(3x5x + 2)\log\left(\frac{3x}{5x\ +\ 2}\right)  

 log⁡(5x + 23x)\log\left(\frac{5x\ +\ 2}{3x}\right)  

 log⁡(3x(5x+2))\log\left(3x\left(5x+2\right)\right)  

 log⁡(5x + 23 − x)\log\left(\frac{5x\ +\ 2}{3\ -\ x}\right)
