The exponent tells you how many times the base is used as a factor.
10^4 = 10 x 10 x 10 x 10

A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.
LPF (Low Power Factor) and UPF (Unity Power Factor) wattmeters are instruments used to measure electrical power in AC circuits. LPF wattmeters are designed for circuits with low power factor, where the phase difference between voltage and current is significant, while UPF wattmeters are used for circuits operating at or near unity power factor, where the voltage and current are in phase. The choice between the two depends on the power factor of the system being measured, as each type provides accurate readings under its respective conditions.
Two factors reduce the power used by a piece of equipment compared to the volt-amps drawn from the supply: power factor and harmonic factor. Both factors increase the power transmission losses incurred in supplying a given amount of power.The power factor is less than 1 when voltage and current are out of phase with each other.When they are in phase the power equals the volt-amps except for a nonlinear load with a current that is not proportional to voltage. This generates harmonics in the current and the effect is that the power is less than the volt-amps, by an amount equal to the harmonic factor.
Watts = Volts x Current x Power Factor. Power Factor is one for resistive loads and less than one for reactive loads. If you assume 80% load factor on your 10 amp circuit that is 8 amps. So each of three devices would have to operate on 2.66 amps. To do this the applied voltage for each device would have to be 900 volts.

yes
103 = 10 x 10 x 10
5^3 = 5 x 5 x 5
10 to the third power equals 10 times 10 times 10
3 to the third power = 3 x 3 x 3
The power refers to the base and exponent, so to write it as the product (multiplication answer) of the same factor you would expand the exponent for example: 7^2 = 7*7 or 4^6 = 4*4*4*4*4*4.
step 1 write each mixed number as an improper fraction step 2 look for common factor and simplify step 3 multiply write the product as a mixed number
Step 1 : Prime Factorise each number and write in index notation. Step 2 : Multiply the lowest power of each common factor of the given numbers
Each number is called a factor. The answer is the product.
In the equation 4 x 9 = 36, the product (36) is greater (larger) than each factor (4 and 9).
The power of a product states that when you raise a product of factors to a power, you can distribute the exponent to each factor. Mathematically, this is expressed as ((ab)^n = a^n \times b^n). If you have the same factor, such as (a), the expression ((a^m)^n) simplifies to (a^{m \cdot n}). For example, if (a = 2), (m = 3), and (n = 2), then ((2^3)^2 = 2^{3 \cdot 2} = 2^6 = 64).
