How can you express the sixth root of 3 in terms of nested radicals?

• Square root of (cube root of 3)

• Both A and B

• None of the above

• Cube root of (square root of 3)

What is the goal when simplifying radical expressions?

• To multiply all radicals

• To avoid fractions under a radical and radicals in the denominator

• To have radicals in the denominator

• To have fractions under a radical

Why is it important to avoid fractions under a radical?

• It is mathematically incorrect

• It is not considered simplified

• It is harder to calculate

• It makes the expression more complex

What does rationalizing the denominator mean?

• Removing radicals from the denominator

• Removing fractions from the numerator

• Adding radicals to the numerator

• Adding fractions to the denominator
