In this lecture you will cover nth Roots. First, Professor Fraser starts with the Definition of the nth Root before moving into the Principal nth Root and its Index. Lastly, you will dive into Using Absolute Values with the nth Root.
The principal nth
root is the nonnegative root. Exception: If n is odd and the
radicand is negative, the principal nth root is negative.
If the nth root of
an even power is an odd power, take the absolute value of the result
to guarantee that the result is nonnegative.
