When serious work needs to be done with radicals,
they are usually changed to a name that uses exponents,
so that the exponent laws can be used.
Also, this new name for radicals allows them to be approximated on any calculator that has a power key.
Here are the rational exponent names for radicals:
[beautiful math coming... please be patient]
$\sqrt{x} = x^{1/2}$
[beautiful math coming... please be patient]
$\root 3\of{x} = x^{1/3}$
[beautiful math coming... please be patient]
$\root 4\of{x} = x^{1/4}$
[beautiful math coming... please be patient]
$\root 5\of{x} = x^{1/5}$
and so on!
Regardless of the name used, the normal restrictions apply.
For example,
[beautiful math coming... please be patient]
$\,x^{1/2}\,$ is only
defined for
[beautiful math coming... please be patient]
$\,x\ge 0\,$.
