Answer:
The right answer is yes, sometimes a radical can be rational.
Step-by-step explanation:
In theory a radical is a number with the next form: [tex]\sqrt[n]{x}[/tex], the radicals can be rationals when x is written as zn, where z is an integer.
an example of a rational number that can be a radical is [tex]\sqrt[3]{125}=5[/tex]
this is because 125 is a perfect third power of 5 and can be expressed as [tex]5^{3}[/tex], and since 5 is an integer we can say is a rational.
another example is [tex]\sqrt[3]{8}[/tex]
