x raised to a positive power, a is xa where a> 0. If a is an integer then it is equal to x*x*...*x where there are a lots of x.
x raised to a negative power is the same as the reciprocal of x raised to the absolute value of the power. Thus, if b < 0 then xb = 1/x-bwhere -b > 0.
x raised to rational or irrational powers are defined using the power laws.
Another Answer
The terms 'positive' and 'negative' powercan also be used to describe the direction of energy flow. For example, when a generator supplies energy to the grid, we can say that the direction of that energy and, therefore, the rate at which the energy flows (i.e. power) is positive. However, when the grid supplies energy back to the generator (causing it to 'motor'), then the energy (and, therefore, the power) is negative.
