Write The Expression $24^{\frac{1}{2}}$ In Radical Form. □ \square □
Introduction
Radical expressions are a fundamental concept in mathematics, and understanding how to simplify them is crucial for solving various mathematical problems. In this article, we will focus on writing the expression $24^{\frac{1}{2}}$ in radical form. We will explore the properties of exponents and radicals, and provide step-by-step instructions on how to simplify the given expression.
Understanding Exponents and Radicals
Before we dive into simplifying the expression, let's briefly review the concepts of exponents and radicals.
- Exponents: An exponent is a small number that is placed above and to the right of a number, indicating how many times the number should be multiplied by itself. For example, $2^3$ means 2 multiplied by itself 3 times, which equals 8.
- Radicals: A radical is a mathematical expression that involves a root of a number. The most common radical is the square root, denoted by the symbol $\sqrt{}$. For example, $\sqrt{16}$ means the number that, when multiplied by itself, equals 16.
Simplifying $24^{\frac{1}{2}}$
Now that we have a basic understanding of exponents and radicals, let's focus on simplifying the expression $24^{\frac{1}{2}}$. To do this, we need to apply the property of exponents that states $a^{\frac{1}{n}} = \sqrt[n]{a}$.
Using this property, we can rewrite the expression as $\sqrt[2]{24}$, which is equivalent to $\sqrt{24}$.
Simplifying the Square Root of 24
To simplify the square root of 24, we need to find the largest perfect square that divides 24. In this case, the largest perfect square that divides 24 is 4.
We can rewrite 24 as $4 \times 6$, and then take the square root of each factor:
Therefore, the simplified form of $24^{\frac{1}{2}}$ is $2\sqrt{6}$.
Conclusion
In this article, we have learned how to simplify the expression $24^{\frac{1}{2}}$ in radical form. We have applied the property of exponents that states $a^{\frac{1}{n}} = \sqrt[n]{a}$, and then simplified the square root of 24 by finding the largest perfect square that divides 24.
We have also reviewed the concepts of exponents and radicals, and provided step-by-step instructions on how to simplify the given expression.

Q: What is the difference between a radical and an exponent?
A: A radical is a mathematical expression that involves a root of a number, while an exponent is a small number that is placed above and to the right of a number, indicating how many times the number should be multiplied by itself.
Q: How do I simplify a radical expression?
A: To simplify a radical expression, you need to find the largest perfect square that divides the number inside the radical. You can then rewrite the number as a product of the perfect square and the remaining factor, and take the square root of each factor.
Q: What is the property of exponents that states $a^{\frac{1}{n}} = \sqrt[n]{a}$?
A: This property states that any number raised to the power of 1/n can be rewritten as the nth root of the number. For example, $2^{\frac{1}{2}}$ can be rewritten as $\sqrt{2}$.
Q: How do I simplify the square root of a number that is not a perfect square?
A: To simplify the square root of a number that is not a perfect square, you need to find the largest perfect square that divides the number, and then rewrite the number as a product of the perfect square and the remaining factor. You can then take the square root of each factor.
Q: What is the difference between a square root and a cube root?
A: A square root is the root of a number that is raised to the power of 1/2, while a cube root is the root of a number that is raised to the power of 1/3.
Q: How do I simplify a radical expression with a cube root?
A: To simplify a radical expression with a cube root, you need to find the largest perfect cube that divides the number inside the radical. You can then rewrite the number as a product of the perfect cube and the remaining factor, and take the cube root of each factor.
Q: Can I simplify a radical expression with a fraction?
A: Yes, you can simplify a radical expression with a fraction by finding the largest perfect square or perfect cube that divides the numerator and denominator, and then rewriting the fraction as a product of the perfect square or perfect cube and the remaining factor.
