The question is probably showing how to multiply numbers that are to powers but have different bases that are factors of each other using power rules rather than a calculator.
Example:
2^13 x 8^2 =
2^13 x (2^3)^2 =
2^13 x 2^6 =
2^(13+6) =
2^(19).
You can double-check answers with a calculator.
Fo is calculated considering product pH, z- value and product residence time calculated considering safety factor of 0.8 to 0.5 to get average velocity. D. A. Nirhali IIT, Kharagpur
You cannot because the value of "the number" has not been specified.
the power of 10
With the factor 4a plus 8b 16c you can find the answer and check it mentally. You would first have to find he product of all the numbers to find the value of the letter A.
Present value annuity factor calculates the current value of future cash flows. The present value factor is used to describe only the current cash flows.
Three to the third power equals three times three times three equals twenty-seven. 3^3 = 3 x 3 x 3 = 27
16 x 16 x 16 = 4096
10 x 10 x 10 = 1000
The product will have the same sign as the given fraction. Also, if it is a proper fraction, then the absolute value of the product will be between the absolute value of the fraction and the factor.
Negative
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.
Power factor value varies from zero to one depending upon the angle between vectorial value of voltage & current and equals to cos fi ( where fi is the angle between i & v)
Power factor value varies from zero to one depending upon the angle between vectorial value of voltage & current and equals to cos fi ( where fi is the angle between i & v)
If that's y to the zero power, the value is 8.
Usually for a power factor lower that 90% a service charge will be added to the monthly electrical bill. On power factor correction calculations try to get the power factor up to 95%.
0. Power factor has to do with the amount of real power. if you have a purely capacitive load, there is no real power flow, thus pf = 0. For purely resistive load, power factor will be 1.0.
Your question cannot be answered, unless the power factor of the load is specified. Since true power(measured in watts) is the product of apparent power(measured in volt amperes) and the power factor of the load.So, given your figure of an apparent power of 20 kV.A(not 'kva'*), the corresponding value of true power could (theoretically!) range from20 kW at a power factor of 1.0, to0 kW at a power factor of 0.(*The correct symbol for kilovolt ampere is 'kV.A', not 'kva', and the correct symbol for kilowatt is 'kW', not 'kw'.)
