What is power law formula?

The power law formula describes a relationship between two quantities where one quantity varies as a power of another. It can be expressed mathematically as ( y = kx^n ), where ( y ) and ( x ) are the variables, ( k ) is a constant, and ( n ) is the exponent that determines the nature of the relationship. Power laws are commonly observed in various fields, including economics, Biology, and physics, illustrating phenomena like wealth distribution and the sizes of cities.
