Find all non-negative rational solutions of the equation:
$$x^y\cdot y^x = y^y$$
$$x^y\cdot y^x = y^y$$
A solution is a homogeneous mixture made up of a solute (the substance being dissolved) and a solvent (the substance doing the dissolving). It can be a solid, liquid, or gas and the components are evenly distributed at a molecular level.
Solutions are formed through a process called dissolution, where the solute particles disperse and become surrounded by the solvent particles. This happens due to the attractive forces between the solute and solvent molecules, which overcome the attractive forces between the solute particles.
There are three main types of solutions - solid solutions, liquid solutions, and gaseous solutions. Solid solutions are formed when a solid solute is dissolved in a solid solvent, such as alloys. Liquid solutions are formed when a solute is dissolved in a liquid solvent, such as saltwater. Gaseous solutions are formed when a gas solute is dissolved in a gas solvent, such as air.
Solutions can be classified as saturated, unsaturated, or supersaturated. A saturated solution is one in which the maximum amount of solute has been dissolved in the solvent at a particular temperature. An unsaturated solution has less solute than the maximum amount that can be dissolved. A supersaturated solution contains more solute than it can normally hold at a particular temperature.
The solubility of a solute is affected by several factors, including temperature, pressure, and the nature of the solute and solvent. Generally, an increase in temperature and/or pressure can increase the solubility of a solute. Additionally, the polarity and molecular size of the solute and solvent can also affect solubility.
