Dividing powers of the same numberCopy the text below in to your books and then answer the
questions
When dividing:Powers of the same base (number) are subtracted.
In general: am ÷ an = am -
n
a) 25 ÷ 22 =
b) 47 ÷ 45 =
c) 62 ÷ 6 =
d) 84 ÷ 83 =
e) 311 ÷ 35 =
f) 2-3 ÷ 2 =
g) 55 ÷ 5 –7 =
h) 11 -2 ÷ 113 =
i) 7-4 ÷ 7-3 =
