The zeroth power of 8 is one, so the sum of two zeroth powers of 8 is two, so the original formula is: 8- 1- 1=6.

Power refers to the result of power operation. N m indicates that the formula indicates m n times. The result of taking n m as a power is called the m power of n.

The zeroth power of all numbers except 0 is 1.

N 0 = 1, when the index is 1, it is usually not written because it is the same as the bottom value; When the index is 2 or 3, it can be read as "the square of n"

Power comparison method:

I. Computational comparison method

First, calculate the power, and then compare it according to the size of the results.

Second, the radix comparison method

In the case of the same exponent, the size of two powers can be determined by comparing the size of the base.

Third, the index comparison method

In the case of the same cardinality, we can determine the size of two powers by comparing the sizes of exponents.

Fourth, the difference comparison method

Subtract the two powers, and determine the size of the two powers according to the comparison between the difference and 0.

Verb (abbreviation of verb) quotient comparison method

Divide the two powers, and then compare the two powers through the relationship between quotient and 1.
