Introduction

In mathematics, expressions involving exponents and powers are a fundamental concept. When dealing with expressions like (3215)5\left(32^{\frac{1}{5}}\right)^5, it's essential to understand the rules of exponents and how to simplify them. In this article, we will evaluate the given expression and explore the underlying mathematical concepts.

Understanding Exponents

Exponents are a shorthand way of representing repeated multiplication. For example, 232^3 means 22 multiplied by itself 33 times, which is equal to 88. When dealing with expressions involving exponents, it's crucial to understand the rules of exponentiation.

The Power of a Power Rule

One of the fundamental rules of exponents is the power of a power rule, which states that when raising a power to another power, we multiply the exponents. Mathematically, this can be represented as:

(am)n=amn(a^m)^n = a^{m \cdot n}

where aa is the base, mm is the exponent, and nn is the power.

Applying the Power of a Power Rule

Now, let's apply the power of a power rule to the given expression:

(3215)5\left(32^{\frac{1}{5}}\right)^5

Using the power of a power rule, we can rewrite the expression as:

3215532^{\frac{1}{5} \cdot 5}

Simplifying the Expression

Now, let's simplify the expression by multiplying the exponents:

32155=32132^{\frac{1}{5} \cdot 5} = 32^1

Evaluating the Expression

Now that we have simplified the expression, we can evaluate it by raising 3232 to the power of 11:

321=3232^1 = 32

Conclusion

In conclusion, the expression (3215)5\left(32^{\frac{1}{5}}\right)^5 can be evaluated by applying the power of a power rule and simplifying the expression. The final result is 3232. This example illustrates the importance of understanding the rules of exponents and how to apply them to simplify complex expressions.

Additional Examples

To further illustrate the concept, let's consider a few additional examples:

  • (23)4=234=212\left(2^3\right)^4 = 2^{3 \cdot 4} = 2^{12}
  • (52)3=523=56\left(5^2\right)^3 = 5^{2 \cdot 3} = 5^6
  • (1012)4=10124=102\left(10^{\frac{1}{2}}\right)^4 = 10^{\frac{1}{2} \cdot 4} = 10^2

These examples demonstrate the power of the power of a power rule in simplifying complex expressions.

Real-World Applications

The concept of exponents and the power of a power rule has numerous real-world applications. For example:

  • In finance, exponents are used to calculate compound interest and investment returns.
  • In science, exponents are used to represent large numbers and to simplify complex calculations.
  • In engineering, exponents are used to calculate stress and strain on materials.

Final Thoughts

In conclusion, the expression (3215)5\left(32^{\frac{1}{5}}\right)^5 can be evaluated by applying the power of a power rule and simplifying the expression. The final result is 3232. This example illustrates the importance of understanding the rules of exponents and how to apply them to simplify complex expressions.

Introduction

In our previous article, we evaluated the expression (3215)5\left(32^{\frac{1}{5}}\right)^5 using the power of a power rule. In this article, we will answer some frequently asked questions about evaluating expressions with exponents.

Q: What is the power of a power rule?

A: The power of a power rule is a fundamental rule of exponents that states when raising a power to another power, we multiply the exponents. Mathematically, this can be represented as:

(am)n=amn(a^m)^n = a^{m \cdot n}

where aa is the base, mm is the exponent, and nn is the power.

Q: How do I apply the power of a power rule?

A: To apply the power of a power rule, simply multiply the exponents. For example, if we have the expression (23)4\left(2^3\right)^4, we can rewrite it as:

234=2122^{3 \cdot 4} = 2^{12}

Q: What if I have a negative exponent?

A: If you have a negative exponent, you can rewrite it as a positive exponent by taking the reciprocal of the base. For example, if we have the expression 232^{-3}, we can rewrite it as:

123=18\frac{1}{2^3} = \frac{1}{8}

Q: Can I simplify expressions with multiple exponents?

A: Yes, you can simplify expressions with multiple exponents by applying the power of a power rule multiple times. For example, if we have the expression (23)422\left(2^3\right)^4 \cdot 2^2, we can rewrite it as:

23422=21222=2142^{3 \cdot 4} \cdot 2^2 = 2^{12} \cdot 2^2 = 2^{14}

Q: How do I evaluate expressions with fractional exponents?

A: To evaluate expressions with fractional exponents, you can rewrite them as a power of a power. For example, if we have the expression 2122^{\frac{1}{2}}, we can rewrite it as:

(212)2=21=2\left(2^{\frac{1}{2}}\right)^2 = 2^1 = 2

Q: Can I use the power of a power rule with different bases?

A: Yes, you can use the power of a power rule with different bases. For example, if we have the expression (32)4\left(3^2\right)^4, we can rewrite it as:

324=383^{2 \cdot 4} = 3^8

Q: What if I have a zero exponent?

A: If you have a zero exponent, the expression is equal to 1. For example, if we have the expression 202^0, we can rewrite it as:

20=12^0 = 1

Q: Can I use the power of a power rule with negative bases?

A: Yes, you can use the power of a power rule with negative bases. For example, if we have the expression (23)4\left(-2^3\right)^4, we can rewrite it as:

(2)34=(2)12(-2)^{3 \cdot 4} = (-2)^{12}
