An exponent
is a shorthand
notation which
tells how many
times a
number (or
expression)
is
multiplied by
itself .
For example
, the number
2
raised to
the
3^{rd}
power
means
that the number two
is multiplied by
itself three
times:
The two in the
expression is called
the base ,
and the 3 is called
the exponent
(or power).
The
"Radical
Symbol"
is a shorthand
notation which
stands
for the roots
of the number
(or
expression)
in the
radicand.
For
example
, the cube
root of
8
stands
for the
number that can be
multiplied by itself
three times (cubed)
to equal 8:
Since,
2 * 2
* 2 =
8, the cube root of
8 is 2.
The 3
in the expression is
called the
root
index , and
the 8 is called the
radicand
.
The
denominator of a
"fractional
power"
is a shorthand
notation which
stands for a
radical
symbol .
For
example
, the cube
root of
8 can
be written:
A power which
is a
"decimal"
is also a shorthand
notation which
stands for a
radical
symbol .
For
example
, the cube
root of
8 can
be written:
