Penjelasan dengan langkah-langkah:
a.Bilangan berpangkat 0 = 1
11^0+12^0+...20^0
=1+1+1+1+1+1+1+1+1+1
=10
b.2^-1+4^-1+8^-1
=½+¼+⅛
=4/8 + 2/8 + 1/8
=7/8
c.10^-2+100^-1+1000^0
=1/10² + 1/100 + 1
=2/100+1
=102/100
d.2^-2-5^-2
=1/2² - 1/5²
=¼-1/25
=21/100
e.3^-3-9^-2
=1/3³ - 1/9²
=1/27 - 1/81
=3/81 - 1/81
=2/81
