Exponents show you how many times to use the
number in multiplication or how many tims the base
is used as a factor. Exponents are also call powers.
In words:
Exponents are shorthand for repeated multiplication
of the same number by itself.

The exponent 2 in the example above tells how many times
the base 8
(the factor) is being multiplied.
example: 8  = 8 × 8 = 64

A number Squared - Any number raised to the second power
is called squared. Example:
The 8 above is "8 squared."
A number Cubed - Any number raised to the third power is
called cubed. Example:
The 5 below is "5 cubed."
Writing numbers:
The chart below shows numbers written in exponential form, factor form
and their standard form.
Rules to remember:
Any number raised to the zero power equal 1 (except zero). example: 12   = 0

Any number raised to the first is equal to itself. example: 9  = 9
