2-3 12 3 1222 18 0125. A negative exponent just means that the base is on the wrong side of the fraction line so you need to flip the base to the other side. Sign conventions edit The above discussion shows that choosing the reference directions of the voltage and current variables in a component determines the direction of power flow that is considered positive.
As given in the below screenshot of a state load dispatch center real time data there are some ICT loadings showing negative activereactive power load. This becomes 3 3 1 3 3 1 27 so you do get the same answer. If the power comes out negative the component is a source converting some other form of power to electric power.

PgenPused0 if we assume the P used is positive then Pgen will be shown as negative. A negative exponent means how many times to divide by the number. 1 5 5 5 153 1125 0008.
Remember that in the source the current flows from the minus to the plus terminal. In a simple battery circuit the ground point is usually the minus terminal of the battery. Negative Exponent Rule this says that negative exponents in the numerator get moved to the denominator and become positive exponents.
So if someone says that this point is 5V they usually mean its 5V compared to ground. So the power is negative. 4x 2x³ via definition of negative exponent What you appear to have done with ddx x³ x⁵ is taken the derivative of the numerator and denominator independent of each other.
B-n 1 b n. A negative power factor occurs when the device which is normally the load generates power which then flows back towards the source which is normally considered the generator.
