In mathematics, exponential expressions and roots are fundamental concepts that are used to describe various mathematical relationships. Exponential expressions are used to represent repeated multiplication of a number, while roots are used to find the value that, when raised to a certain power, gives a specified value. In this article, we will explore which exponential expression is equivalent to $\sqrt[7]{b}$.

What is a Root?

A root is a value that, when raised to a certain power, gives a specified value. For example, the square root of a number is a value that, when multiplied by itself, gives the original number. In mathematical notation, the square root of a number $a$ is denoted by $\sqrt{a}$.

What is an Exponential Expression?

An exponential expression is a mathematical expression that represents repeated multiplication of a number. For example, $2^3$ represents the repeated multiplication of 2 by itself three times, which equals 8. Exponential expressions are used to describe various mathematical relationships, such as growth and decay.

Equivalence of Exponential Expressions and Roots

In mathematics, exponential expressions and roots are equivalent in the sense that they can be used to represent the same mathematical relationship. For example, the square root of a number $a$ can be represented as $a^{\frac{1}{2}}$, which is an exponential expression.

Which Exponential Expression is Equivalent to $\sqrt[7]{b}$?

To determine which exponential expression is equivalent to $\sqrt[7]{b}$, we need to understand the relationship between roots and exponential expressions. The root of a number $b$ with a power of 7 can be represented as $b^{\frac{1}{7}}$, which is an exponential expression.

Analyzing the Options

Let's analyze the options given:

A. $\frac{1}{b^{\frac{1}{7}}}$ B. $\frac{1}{b^7}$ C. $b^7$ D. $b^{\frac{1}{7}}$

Option A: $\frac{1}{b^{\frac{1}{7}}}$

This option represents the reciprocal of the exponential expression $b^{\frac{1}{7}}$. However, this is not equivalent to the root of $b$ with a power of 7.

Option B: $\frac{1}{b^7}$

This option represents the reciprocal of the exponential expression $b^7$. However, this is not equivalent to the root of $b$ with a power of 7.

Option C: $b^7$

This option represents the exponential expression $b^7$, which is not equivalent to the root of $b$ with a power of 7.

Option D: $b^{\frac{1}{7}}$

This option represents the exponential expression $b^{\frac{1}{7}}$, which is equivalent to the root of $b$ with a power of 7.

Conclusion

In conclusion, the exponential expression that is equivalent to $\sqrt[7]{b}$ is $b^{\frac{1}{7}}$. This is because the root of a number $b$ with a power of 7 can be represented as $b^{\frac{1}{7}}$, which is an exponential expression.

Final Answer

In the previous article, we discussed the equivalence of exponential expressions and roots, and determined that the exponential expression $b^{\frac{1}{7}}$ is equivalent to $\sqrt[7]{b}$.
