Theory:

The power operation is recorded as follows:

a.svg - base;
 
b.svg - exponent;
 
c.svg - the result of the increment or the value of the degree
 
Read as: "\(a\) to the power \(b\) equals \(c\)".
 
Calculating a step value is called stepping!

If the magnifier is a natural number.

The positive value of a positive integer is always positive.
32=33=9
 
253=252525=8125
A negative number is positive if the multiplier is an even number and negative if the multiplier is an odd number.
(3)4=(3)(3)(3)(3)=81
 
(3)3=(3)(3)(3)=27
 
Important!
Distinguish some seemingly similar notes (2)4 and 24. In the first case, the minus sign is the base sign \((-2)\) and in the second case, the degree sign (base is \(2\)).
(2)4=(2)(2)(2)(2)=16
 
24=(2222)=16.
