Answer:
Step-by-step explanation:
When a number is raised to a <em>rational</em> number like , that is, a fraction, the <em>denominator</em> represents the <em>index</em> of the radical (or commonly known as the root nth of the radical), and the <em>numerator</em> represents the number to which the radicand (the part of the expression inside the radical sign) is about to be raised.
Looking at , the <em>index</em> (root) of the radical is 4 and the numerator raises the value of x to the third power, that is, . That explains the answer: six (6) times . The six (6) only multiplies the expression.
Likewise, a radical of index 5, with a radicand raised to the ninth power is represented by , which is equivalent to .
By the way, a particular case is when the index is 2, that is, . Here, the number <em>2</em> is omitted from the radical symbol and is represented by .
