There are several equations that involve power. The basic definition of power is energy divide by time, so that is one equation. In electricity, if you have a DC current, power = current x voltage. In the case of AC, power = current x voltage x power factor (in many cases, the power factor is close to 1).
What else can I help you with?
What is an equation that involves a number raised to a variable power?
An exponential equation.
What is the Solution of logarithmic equation?
The answer to the question depends on the nature of the equation. Generally speaking it will involve exponentiation (raising the log base to a power).
How do you know if a equation is a quadratic one?
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
