Definition of degree if the magnifier is a negative integer
A fraction with a whole negative multiplier is taken to be a fraction with a numerator of \(1\), but the denominator is the same base with the opposite positive multiplier.
Example:
an=1an(nanynonzerorealnumber)
Exceptions are the degree of \(0\) with a negative multiplier, 03 and 01.
32=132=19
 
101=1101=110=0.1
 
(4)3=1(4)3=164=164
 
(1)3=1(1)3=11=1
Important!
When increasing the share to a negative degree, the law shall be used:  abn=ban
233=323=278=338
