1.39 times 10 to the 2nd power is 139
Power = energy/time = 50/5 = 10 watts
if it is to the 2nd power it is 64 if it is to the 3rd power it is 512 .
400
The answer is 2x5x5 or 2x 5 to the 2nd power
50 to the 3rd power is the same as 50 x 50 x 50=? try to figure it out.(i know what it is. That is the same with anything because power (1st, 2nd , or 3rd, ect.) is that number times itself how ever many powers. keep that in mind.
91 to the 2nd power is 8,281.
21 to the 2nd power is 441.
50
4 to the 2nd power in exponents is 42

503 = 50 * 50 * 50 = 125,000.

If a load takes 50 kW at a power factor of 0.5 lagging calculate the apparent power and reactive power Answer: Apparent power = Active power / Power Factor In this case, Active power = 50 kW and power factor = 0.5 So Apparent power = 50/0.5 = 100 KVA
50 = 10log(50) = 101.69897 (approx)
4C2 * (-2CD2) = -8C3D2
