Power refers to the result of power operation. N m indicates that the formula indicates m n times. The result of taking m of n as a power is called m power of n, also called m power of n.
Power does not conform to the associative law and commutative law. Power refers to the cloth that covers things. In mathematics, "power" is the result of power, and the expression of power is realized by adding the form of goal to a number, so it is like "covering a scarf" on a number.
Size comparison method:
Computational comparison method:
First, calculate the power, and then compare it according to the size of the results.
Basic comparison method:
In the case of the same exponent, the size of two powers can be determined by comparing the size of the base.
Exponential comparison method:
In the case of the same cardinality, we can determine the size of two powers by comparing the sizes of exponents.
Differential comparison method:
Subtract the two powers, and determine the size of the two powers according to the comparison between the difference and 0.
Quotient comparison method:
Divide the two powers, and then compare the two powers through the relationship between quotient and 1.
