Introduction

In mathematics, exponential form is a way of expressing repeated multiplication of a number. It is a shorthand method of writing expressions that involve repeated multiplication of the same base. In this article, we will explore how to rewrite expressions in exponential form and apply this concept to a specific problem.

What is Exponential Form?

Exponential form is a way of expressing repeated multiplication of a number. It is written in the form of $a^b$ , where $a$ is the base and $b$ is the exponent. The exponent tells us how many times the base is multiplied by itself. For example, $2^3$ means $2$ multiplied by itself $3$ times, which is equal to $2 \times 2 \times 2 = 8$ .

Rewriting Expressions in Exponential Form

To rewrite an expression in exponential form, we need to identify the base and the exponent. The base is the number that is being multiplied by itself, and the exponent is the number of times the base is multiplied by itself.

For example, consider the expression $m \cdot m \cdot m \cdot m \cdot m$ . To rewrite this expression in exponential form, we need to identify the base and the exponent. In this case, the base is $m$ and the exponent is $5$ , because the expression involves $5$ repeated multiplications of the base $m$ .

Applying the Concept to the Problem

Now that we have a good understanding of how to rewrite expressions in exponential form, let's apply this concept to the problem at hand. The problem asks us to rewrite the expression $m \cdot m \cdot m \cdot m \cdot m$ in exponential form.

Using the concept we learned earlier, we can rewrite this expression as $m^5$ . This is because the expression involves $5$ repeated multiplications of the base $m$ .

Evaluating the Answer Choices

Now that we have rewritten the expression in exponential form, let's evaluate the answer choices to see which one is correct.

A. $m^5$ - This is the correct answer, because it is the exponential form of the expression $m \cdot m \cdot m \cdot m \cdot m$ .

B. $5m$ - This is not the correct answer, because it is not the exponential form of the expression $m \cdot m \cdot m \cdot m \cdot m$ .

C. $5^m$ - This is not the correct answer, because it is not the exponential form of the expression $m \cdot m \cdot m \cdot m \cdot m$ .

D. $m+5$ - This is not the correct answer, because it is not the exponential form of the expression $m \cdot m \cdot m \cdot m \cdot m$ .

Conclusion

In conclusion, rewriting expressions in exponential form is a fundamental concept in mathematics that allows us to express repeated multiplication of a number in a concise and efficient way. By applying this concept to the problem at hand, we were able to rewrite the expression $m \cdot m \cdot m \cdot m \cdot m$ in exponential form as $m^5$ . This demonstrates the importance of understanding exponential form in mathematics and how it can be applied to solve problems.

Introduction

Exponential form is a fundamental concept in mathematics that allows us to express repeated multiplication of a number in a concise and efficient way. In this article, we will answer some of the most frequently asked questions about exponential form and provide examples to help illustrate the concept.

Q: What is exponential form?

A: Exponential form is a way of expressing repeated multiplication of a number. It is written in the form of $a^b$ , where $a$ is the base and $b$ is the exponent. The exponent tells us how many times the base is multiplied by itself.

Q: How do I rewrite an expression in exponential form?

A: To rewrite an expression in exponential form, you need to identify the base and the exponent. The base is the number that is being multiplied by itself, and the exponent is the number of times the base is multiplied by itself.

For example, consider the expression $m \cdot m \cdot m \cdot m \cdot m$ . To rewrite this expression in exponential form, you would identify the base as $m$ and the exponent as $5$ , because the expression involves $5$ repeated multiplications of the base $m$ . Therefore, the exponential form of this expression is $m^5$ .

Q: What is the difference between $a^b$ and $b^a$ ?

A: The difference between $a^b$ and $b^a$ is the order in which the base and exponent are written.

For example, consider the expression $2^3$ . This means that $2$ is being multiplied by itself $3$ times, which is equal to $2 \times 2 \times 2 = 8$ .

On the other hand, consider the expression $3^2$ . This means that $3$ is being multiplied by itself $2$ times, which is equal to $3 \times 3 = 9$ .

Q: Can I have a negative exponent?

A: Yes, you can have a negative exponent. A negative exponent means that the base is being divided by itself the number of times specified by the exponent.

For example, consider the expression $2^{-3}$ . This means that $2$ is being divided by itself $3$ times, which is equal to $\frac{1}{2 \times 2 \times 2} = \frac{1}{8}$ .

Q: Can I have a fractional exponent?

A: Yes, you can have a fractional exponent. A fractional exponent means that the base is being raised to a power that is a fraction.

For example, consider the expression $2^{\frac{1}{2}}$ . This means that $2$ is being raised to the power of $\frac{1}{2}$ , which is equal to the square root of $2$ .

Q: Can I have a zero exponent?

A: Yes, you can have a zero exponent. A zero exponent means that the base is being raised to the power of $0$ , which is equal to $1$ .

For example, consider the expression $2^0$ . This means that $2$ is being raised to the power of $0$ , which is equal to $1$ .

Q: Can I have a negative base?

A: Yes, you can have a negative base. A negative base means that the base is a negative number.

For example, consider the expression $(-2)^3$ . This means that $-2$ is being multiplied by itself $3$ times, which is equal to $-2 \times -2 \times -2 = -8$ .
