PENGERTIAN EKSPONEN
◦Jika a sebuah bilangan real dan n merupakan bilangan bulat maka yang disebut an (dibaca a pangkat n) adalah perkalian bilangan a dengan dirinya sendiri sebanyak n foktor. Dinyatakan dengan lambang:
an = a x a x a x a x ........x a sebanyak n faktor

Some text here about the topic of discussion
◦Keterangan:
an = Bilangan berpangkat
a = bilangan pokok
n = pangkat/eksponen
3
JENIS PANGKAT
◦Pangkat bulat positif
◦Contoh:
a5 = a x a x a x a x a
43 = 4 x 4 x 4 x 4 = 64
-53 = (-5) x (-5) x (-5) = -125
