A. Eksponen
1) Negative and zero powers
Suppose a  R and a  0, then:
1 1
a) a–n = or an =
an a−n
b) a0 = 1


2) Rank Traits
If a and b are real numbers and n, p, q are positive integers, then applicable:
a) ap: aq = ap–q
b) ap× aq = ap+q

c) (a p )q = a pq


d) (a  b )n = an×bn

e) (ba )n = ba n
n
