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.
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).
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.
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.
The product would be: (10^{10} ) Jupiter hours. The value of the power is: ( 10,000,000,000 ) hours.
Negative
Power Factor = KVA/KW. This has no unit. Its value is always 1 or less.
Power = volts x amperes x power factor. However, VA or kVA is simply the product of volts x amperes, and does not take into account the power factor. Note that in many practical situations, the power factor is close to 1.
If that's y to the zero power, the value is 8.
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)

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%.
