Understanding the Problem

When dealing with exponents and roots, it's essential to understand the properties and rules that govern them. In this problem, we're given the expression $$24^{\frac{1}{3}}$$ and asked to find an equivalent expression from the given options. To solve this, we need to apply the rules of exponents and roots, specifically the rule for fractional exponents.

Fractional Exponents

A fractional exponent is a shorthand way of expressing a root. For example, $$a^{\frac{1}{n}}$$ is equivalent to $$\sqrt[n]{a}$$. This rule allows us to rewrite the given expression in a more familiar form.

Rewriting the Expression

Using the rule for fractional exponents, we can rewrite $$24^{\frac{1}{3}}$$ as $$\sqrt[3]{24}$$. This is because the exponent $$\frac{1}{3}$$ indicates that we need to take the cube root of the number inside the radical.

Simplifying the Radical

Now that we have $$\sqrt[3]{24}$$, we can simplify the radical by factoring the number inside it. We can write $$24$$ as $$2^3 \cdot 3$$, which means that $$\sqrt[3]{24}$$ is equivalent to $$\sqrt[3]{2^3 \cdot 3}$$.

Applying the Rule for Radicals

When we have a product inside a radical, we can take the cube root of each factor separately. This means that $$\sqrt[3]{2^3 \cdot 3}$$ is equivalent to $$\sqrt[3]{2^3} \cdot \sqrt[3]{3}$$.

Simplifying the Expression

Now that we have $$\sqrt[3]{2^3} \cdot \sqrt[3]{3}$$, we can simplify the expression further. The cube root of $$2^3$$ is simply $$2$$, so we're left with $$2 \cdot \sqrt[3]{3}$$.

Comparing with the Options

Now that we have $$2 \cdot \sqrt[3]{3}$$, we can compare it with the given options. The only option that matches this expression is $$2 \sqrt[3]{3}$$.

Conclusion

In conclusion, the expression $$24^{\frac{1}{3}}$$ is equivalent to $$2 \sqrt[3]{3}$$. This is because we can rewrite the expression using the rule for fractional exponents, simplify the radical, and apply the rule for radicals to get the final result.

Final Answer

The final answer is: $\boxed{2 \sqrt[3]{3}}$
