What is the Exponential Form of the Expanded Form Below?

Understanding Exponents and Expanded Forms

In mathematics, exponents are a shorthand way of representing repeated multiplication. The expanded form of an expression is the expression written out in full, with each term multiplied together. For example, the expanded form of $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ is a product of six factors, each of which is the number 4.

The Exponential Form of the Expanded Form

To find the exponential form of the expanded form $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ , we need to understand the concept of exponents. The exponent of a number is the power to which the number is raised. In this case, we have six factors of 4, so we can write the expanded form as $4^6$ .

Why is the Exponential Form $4^6$ ?

The exponential form $4^6$ is the result of raising 4 to the power of 6. This means that we are multiplying 4 by itself 6 times. For example, $4^6 = 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ . This is equivalent to the expanded form $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ .

Why is $4^{-6}$ Not the Correct Answer?

The option $4^{-6}$ is not the correct answer because it represents a negative exponent. A negative exponent is the reciprocal of the positive exponent. For example, $4^{-6} = \frac{1}{4^6}$ . This is not equivalent to the expanded form $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ .

Why is $4^3$ Not the Correct Answer?

The option $4^3$ is not the correct answer because it represents a different exponent. The exponent 3 is not equivalent to the exponent 6, which is the exponent of the expanded form $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ .

Why is $6^4$ Not the Correct Answer?

The option $6^4$ is not the correct answer because it represents a different base and exponent. The base 6 is not equivalent to the base 4, and the exponent 4 is not equivalent to the exponent 6.

Conclusion

In conclusion, the exponential form of the expanded form $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ is $4^6$ . This is because the exponent 6 represents the power to which the number 4 is raised. The other options, $4^{-6}$ , $4^3$ , and $6^4$ , are not the correct answers because they represent different exponents or bases.

Understanding Exponents and Expanded Forms

Exponents are a shorthand way of representing repeated multiplication. The expanded form of an expression is the expression written out in full, with each term multiplied together. For example, the expanded form of $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ is a product of six factors, each of which is the number 4.

The Importance of Exponents

Exponents are an important concept in mathematics because they allow us to represent repeated multiplication in a concise way. They are used in a wide range of mathematical operations, including multiplication, division, and exponentiation.

How to Use Exponents

To use exponents, we need to understand the concept of exponents and how to represent repeated multiplication. We can use exponents to represent a product of factors, such as $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ . We can also use exponents to represent a power of a number, such as $4^6$ .

Common Exponent Rules

There are several common exponent rules that we need to understand in order to use exponents effectively. These rules include:

Product of Powers Rule: When we multiply two powers with the same base, we add the exponents. For example, $4^6 \cdot 4^3 = 4^{6+3} = 4^9$ .
Power of a Power Rule: When we raise a power to a power, we multiply the exponents. For example, $(4^6)^3 = 4^{6 \cdot 3} = 4^{18}$ .
Quotient of Powers Rule: When we divide two powers with the same base, we subtract the exponents. For example, $\frac{4^6}{4^3} = 4^{6-3} = 4^3$ .

Conclusion

In conclusion, exponents are an important concept in mathematics that allow us to represent repeated multiplication in a concise way. We can use exponents to represent a product of factors, such as $4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4$ , or a power of a number, such as $4^6$ . We need to understand the common exponent rules, including the product of powers rule, the power of a power rule, and the quotient of powers rule, in order to use exponents effectively.

Final Answer

The final answer is $4^6$ .
