1. When adding logarithms you can combine them into one logarithm and make them multiply. When subtracting logarithms you can combine them into one and make them divide. So below I have combined the adding ones to make them multiply and divide everything by subtracting logarithm. Also when you have a number in front of the logarithm you can move it to the front and put it as the power of the logarithm:ln [{x 5}^2] [{y-2}^5] / [xy]^2Sorry it looks complicated
