Introduction

Radical expressions, also known as roots, are a fundamental concept in mathematics. They are used to represent the nth root of a number, where n is a positive integer. In this article, we will explore the concept of radical expressions and learn how to simplify them. We will also apply this knowledge to solve a specific problem involving a radical expression.

What are Radical Expressions?

A radical expression is a mathematical expression that involves a root or a radical sign. The most common radical sign is the square root sign, which is represented by the symbol √. However, there are other types of radical signs, such as the cube root sign (∛) and the fourth root sign (⁴√).

Properties of Radical Expressions

Radical expressions have several properties that make them useful in mathematics. Some of these properties include:

Product Property: The product of two or more radical expressions is equal to the product of the individual radical expressions.
Quotient Property: The quotient of two or more radical expressions is equal to the quotient of the individual radical expressions.
Power Property: The power of a radical expression is equal to the power of the individual radical expression.

Simplifying Radical Expressions

Simplifying radical expressions involves rewriting them in a simpler form. This can be done by using the properties of radical expressions, such as the product property and the power property.

Step 1: Simplify the Expression Inside the Radical Sign

To simplify the expression inside the radical sign, we need to apply the power property. The power property states that the power of a radical expression is equal to the power of the individual radical expression.

In this case, we have the expression $\left(\sqrt[4]{5^3}\right)^{\frac{1}{2}}$ . To simplify this expression, we need to apply the power property.

Step 2: Apply the Power Property

The power property states that the power of a radical expression is equal to the power of the individual radical expression. In this case, we have the expression $\left(\sqrt[4]{5^3}\right)^{\frac{1}{2}}$ . To simplify this expression, we need to apply the power property.

Using the power property, we can rewrite the expression as:

$\left(\sqrt[4]{5^3}\right)^{\frac{1}{2}} = \left(5^{\frac{3}{4}}\right)^{\frac{1}{2}}$

Step 3: Simplify the Expression

Now that we have applied the power property, we can simplify the expression further. To do this, we need to apply the product property.

The product property states that the product of two or more radical expressions is equal to the product of the individual radical expressions. In this case, we have the expression $\left(5^{\frac{3}{4}}\right)^{\frac{1}{2}}$ . To simplify this expression, we need to apply the product property.

Using the product property, we can rewrite the expression as:

$\left(5^{\frac{3}{4}}\right)^{\frac{1}{2}} = 5^{\frac{3}{8}}$

Conclusion

In this article, we learned how to simplify radical expressions using the power property and the product property. We applied this knowledge to solve a specific problem involving a radical expression.

Which Expression is Equivalent to $\left(\sqrt[4]{5^3}\right)^{\frac{1}{2}}$ ?

Based on our analysis, we can conclude that the expression $\left(\sqrt[4]{5^3}\right)^{\frac{1}{2}}$ is equivalent to $5^{\frac{3}{8}}$ .

Answer

The correct answer is B. $5^{\frac{3}{8}}$ .

Discussion

This problem involves simplifying a radical expression using the power property and the product property. The key to solving this problem is to apply the power property and then simplify the expression further using the product property.

Final Thoughts

In conclusion, simplifying radical expressions is an important concept in mathematics. By applying the power property and the product property, we can simplify radical expressions and solve problems involving them.
