17 to the 3rd power as a product of the same factor is written 17 x 17 x 17
n to the 3rd power is n x n x n
(2x - 5)(4x^2 + 10x + 25)
Third
5 to the 3rd power, or 5x5x5. so, 5 is a factor of 125
One dIrection came 3rd in the x factor 2010
x^7
10 is a root of x3 - 1000 = 0, so (x-10) is a factor. Use long division (x3 - 1000)/(x-10) to find x2 + 10x + 100, as the other factor.
In an AC system power is equal to Voltage x Current x Power factor. Power factor is not constant and depends on the type of the load. Ideal value of the Power factor is 1, where as practically remains less then 1.
Numbers with exponents are sometimes referred to as a power. For example, x^4 can be called "x to the fourth power" which means that x is used as a factor four times. So, in a power, the number used as a factor is the base.
x(x - 1)
xxx = x to the 3rd power
