Introduction

In mathematics, we often come across expressions that involve radicals and exponents. These expressions can be simplified using various mathematical operations, and in this article, we will explore two such expressions involving radicals and exponents. We will simplify each expression and determine which one is equal to an integer.

Expression F

The first expression is given by:

F. \frac{\sqrt[3]{32} \sqrt[6]{4}}{\sqrt{2}}

To simplify this expression, we can start by evaluating the cube root of 32 and the sixth root of 4.

\sqrt[3]{32} = \sqrt[3]{2^5} = 2^{\frac{5}{3}}

\sqrt[6]{4} = \sqrt[6]{2^2} = 2^{\frac{1}{3}}

Now, we can substitute these values back into the original expression.

F. \frac{\sqrt[3]{32} \sqrt[6]{4}}{\sqrt{2}} = \frac{2^{\frac{5}{3}} \cdot 2^{\frac{1}{3}}}{\sqrt{2}}

Using the properties of exponents, we can simplify the numerator.

2^{\frac{5}{3}} \cdot 2^{\frac{1}{3}} = 2^{\frac{5}{3} + \frac{1}{3}} = 2^2

Now, we can substitute this value back into the original expression.

F. \frac{\sqrt[3]{32} \sqrt[6]{4}}{\sqrt{2}} = \frac{2^2}{\sqrt{2}}

To simplify the expression further, we can rationalize the denominator by multiplying both the numerator and the denominator by the square root of 2.

\frac{2^2}{\sqrt{2}} \cdot \frac{\sqrt{2}}{\sqrt{2}} = \frac{2^2 \sqrt{2}}{2}

Using the properties of exponents, we can simplify the numerator.

2^2 \sqrt{2} = 2^2 \cdot 2^{\frac{1}{2}} = 2^{\frac{5}{2}}

Now, we can substitute this value back into the original expression.

F. \frac{\sqrt[3]{32} \sqrt[6]{4}}{\sqrt{2}} = \frac{2^{\frac{5}{2}}}{2}

Using the properties of exponents, we can simplify the expression further.

\frac{2^{\frac{5}{2}}}{2} = 2^{\frac{5}{2} - 1} = 2^{\frac{3}{2}}

Expression G

The second expression is given by:

G. \frac{\sqrt{8} \sqrt[3]{16}}{\sqrt[6]{2}}

To simplify this expression, we can start by evaluating the square root of 8 and the cube root of 16.

\sqrt{8} = \sqrt{2^3} = 2^{\frac{3}{2}}

\sqrt[3]{16} = \sqrt[3]{2^4} = 2^{\frac{4}{3}}

Now, we can substitute these values back into the original expression.

G. \frac{\sqrt{8} \sqrt[3]{16}}{\sqrt[6]{2}} = \frac{2^{\frac{3}{2}} \cdot 2^{\frac{4}{3}}}{\sqrt[6]{2}}

Using the properties of exponents, we can simplify the numerator.

2^{\frac{3}{2}} \cdot 2^{\frac{4}{3}} = 2^{\frac{3}{2} + \frac{4}{3}} = 2^{\frac{9}{6} + \frac{8}{6}} = 2^{\frac{17}{6}}

Now, we can substitute this value back into the original expression.

G. \frac{\sqrt{8} \sqrt[3]{16}}{\sqrt[6]{2}} = \frac{2^{\frac{17}{6}}}{\sqrt[6]{2}}

To simplify the expression further, we can rationalize the denominator by multiplying both the numerator and the denominator by the sixth root of 2.

\frac{2^{\frac{17}{6}}}{\sqrt[6]{2}} \cdot \frac{\sqrt[6]{2}}{\sqrt[6]{2}} = \frac{2^{\frac{17}{6}} \sqrt[6]{2}}{2^{\frac{1}{6}}}

Using the properties of exponents, we can simplify the numerator.

2^{\frac{17}{6}} \sqrt[6]{2} = 2^{\frac{17}{6}} \cdot 2^{\frac{1}{6}} = 2^{\frac{18}{6}} = 2^3

Now, we can substitute this value back into the original expression.

G. \frac{\sqrt{8} \sqrt[3]{16}}{\sqrt[6]{2}} = \frac{2^3}{2^{\frac{1}{6}}}

Using the properties of exponents, we can simplify the expression further.

\frac{2^3}{2^{\frac{1}{6}}} = 2^{3 - \frac{1}{6}} = 2^{\frac{17}{6}}

Conclusion

In this article, we simplified two expressions involving radicals and exponents. We found that expression F is equal to $2^{\frac{3}{2}}$ , while expression G is equal to $2^{\frac{17}{6}}$ . Since $2^{\frac{3}{2}}$ is an integer, we can conclude that expression F is equal to an integer.

Comparison of Expressions F and G

In this section, we will compare the two expressions and determine which one is equal to an integer.

As we can see from the previous section, expression F is equal to $2^{\frac{3}{2}}$ , while expression G is equal to $2^{\frac{17}{6}}$ . Since $2^{\frac{3}{2}}$ is an integer, we can conclude that expression F is equal to an integer.

On the other hand, expression G is equal to $2^{\frac{17}{6}}$ , which is not an integer. Therefore, we can conclude that expression G is not equal to an integer.

Final Answer

Based on our analysis, we can conclude that expression F is equal to an integer, while expression G is not equal to an integer.

Key Takeaways

Expression F is equal to $2^{\frac{3}{2}}$ , which is an integer.
Expression G is equal to $2^{\frac{17}{6}}$ , which is not an integer.
To determine which expression is equal to an integer, we need to simplify the expressions and evaluate their values.

Introduction

In our previous article, we simplified two expressions involving radicals and exponents. We found that expression F is equal to $2^{\frac{3}{2}}$ , while expression G is equal to $2^{\frac{17}{6}}$ . Since $2^{\frac{3}{2}}$ is an integer, we can conclude that expression F is equal to an integer. In this article, we will answer some frequently asked questions related to the topic.

Q: What is the difference between expression F and expression G?

A: The main difference between expression F and expression G is the value of the exponents. Expression F has an exponent of $\frac{3}{2}$ , while expression G has an exponent of $\frac{17}{6}$ . This difference in exponents results in different values for the two expressions.

Q: Why is expression F equal to an integer, while expression G is not?

A: Expression F is equal to an integer because its exponent is a rational number that can be simplified to an integer. On the other hand, expression G has an exponent that cannot be simplified to an integer, resulting in a non-integer value.

Q: Can you provide more examples of expressions that are equal to integers?

A: Yes, here are a few examples of expressions that are equal to integers:
