Understanding Exponents and Their Properties

When dealing with exponents, it's essential to understand the properties that govern their behavior. In this case, we're given the product $3^4 \times 3^2$ , and we want to express it as a power of 3. To do this, we need to apply the properties of exponents, specifically the rule for multiplying powers with the same base.

The Rule for Multiplying Powers with the Same Base

When multiplying powers with the same base, we add the exponents. This rule is a fundamental property of exponents and is used extensively in algebra and other branches of mathematics. In the case of the product $3^4 \times 3^2$ , we can apply this rule to simplify the expression.

Applying the Rule for Multiplying Powers with the Same Base

To express the product $3^4 \times 3^2$ as a power of 3, we need to add the exponents. The base is 3, and the exponents are 4 and 2. Using the rule for multiplying powers with the same base, we get:

3^4 \times 3^2 = 3^{4+2} = 3^6

In this expression, we've added the exponents 4 and 2 to get the new exponent 6. This is a key property of exponents, and it allows us to simplify complex expressions involving powers.

Understanding the Concept of Exponentiation

Exponentiation is a fundamental operation in mathematics that involves raising a number to a power. In the case of the expression $3^6$ , we're raising 3 to the power of 6. This means that we need to multiply 3 by itself 6 times:

3^6 = 3 \times 3 \times 3 \times 3 \times 3 \times 3

This expression can be evaluated by multiplying the numbers together, but it's often more convenient to use the properties of exponents to simplify the expression.

Simplifying Exponential Expressions

In many cases, we can simplify exponential expressions by applying the properties of exponents. For example, if we have the expression $3^4 \times 3^2$ , we can simplify it by adding the exponents:

3^4 \times 3^2 = 3^{4+2} = 3^6

This is a key technique for simplifying exponential expressions, and it's used extensively in algebra and other branches of mathematics.

Real-World Applications of Exponents

Exponents have many real-world applications, including finance, science, and engineering. For example, in finance, exponents are used to calculate compound interest and investment returns. In science, exponents are used to describe the growth and decay of populations, as well as the behavior of physical systems. In engineering, exponents are used to design and optimize systems, including electrical circuits and mechanical systems.

Conclusion

In conclusion, the product $3^4 \times 3^2$ can be expressed as a power of 3 by applying the rule for multiplying powers with the same base. This rule states that when multiplying powers with the same base, we add the exponents. By applying this rule, we can simplify complex expressions involving powers and gain a deeper understanding of the properties of exponents.
