Simplifying the Given Statement

Oct 13, 2025 by talynt.org 82 views

Introduction

In mathematics, there are various ways to represent the same value. One such representation is the relationship between roots and exponents. The given statement, $\sqrt[4]{2}=2^{\frac{1}{2}}$ , seems to be a simple equation, but it requires a deeper understanding of the underlying concepts. In this article, we will explore the simplification that accurately explains this statement.

What are Roots and Exponents?

Before diving into the explanation, let's first understand what roots and exponents are.

Roots

A root of a number is a value that, when raised to a certain power, gives the original number. For example, the square root of 16 is 4, because $4^2 = 16$ . Similarly, the cube root of 27 is 3, because $3^3 = 27$ . In general, the nth root of a number is a value that, when raised to the power of n, gives the original number.

Exponents

An exponent is a small number that is raised to a power. For example, $2^3$ means 2 raised to the power of 3, which is equal to 8. Exponents can also be fractional, such as $2^{\frac{1}{2}}$ , which means 2 raised to the power of one-half, or $\sqrt{2}$ .

Simplifying the Given Statement

Now that we have a basic understanding of roots and exponents, let's simplify the given statement.

The Original Statement

The original statement is $\sqrt[4]{2}=2^{\frac{1}{2}}$ . This statement seems to be a simple equation, but it requires a deeper understanding of the underlying concepts.

Simplifying the Left Side

The left side of the equation is $\sqrt[4]{2}$ . This can be simplified as follows:

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

This is because the fourth root of a number is equal to the number raised to the power of one-fourth, raised to the power of 4.

Simplifying the Right Side

The right side of the equation is $2^{\frac{1}{2}}$ . This can be simplified as follows:

$2^{\frac{1}{2}} = \sqrt{2}$

This is because the square root of a number is equal to the number raised to the power of one-half.

Equating the Two Sides

Now that we have simplified both sides of the equation, we can equate them:

$\left(2^{\frac{1}{4}}\right)^4 = \sqrt{2}$

This equation shows that the fourth root of 2 is equal to the square root of 2.

Conclusion

In conclusion, the simplification that accurately explains the given statement is $\left(2^{\frac{1}{4}}\right)^4 = 2^{\frac{1}{4}} \cdot 2^{\frac{1}{4}} \cdot 2^{\frac{1}{4}} \cdot 2^{\frac{1}{4}} = 2$ . This equation shows that the fourth root of 2 is equal to the number 2 raised to the power of one-fourth, multiplied by itself four times.

Discussion

The given statement is a simple equation that requires a deeper understanding of the underlying concepts. The simplification of the left side of the equation shows that the fourth root of 2 is equal to the number 2 raised to the power of one-fourth, raised to the power of 4. The simplification of the right side of the equation shows that the square root of 2 is equal to the number 2 raised to the power of one-half. The equation shows that the fourth root of 2 is equal to the square root of 2.
