Introduction

In mathematics, exponents are a fundamental concept used to represent repeated multiplication of a number. When dealing with complex exponents, it's essential to understand the rules and properties that govern their behavior. In this article, we will delve into the world of complex exponents and explore how to simplify expressions involving exponents.

Understanding Exponents

Exponents are a shorthand way of representing repeated multiplication of a number. For example, the expression $2^3$ can be read as "2 to the power of 3" and is equivalent to $2 \times 2 \times 2$ . Exponents can be positive, negative, or zero, and they can be applied to any real number.

Properties of Exponents

There are several properties of exponents that we need to understand in order to simplify complex expressions. These properties include:

Product of Powers: When multiplying two numbers with the same base, we can add their exponents. For example, $2^3 \times 2^4 = 2^{3+4} = 2^7$ .
Power of a Power: When raising a power to another power, we can multiply the exponents. For example, $(2^3)^4 = 2^{3 \times 4} = 2^{12}$ .
Quotient of Powers: When dividing two numbers with the same base, we can subtract their exponents. For example, $\frac{2^5}{2^3} = 2^{5-3} = 2^2$ .
Zero Exponent: Any number raised to the power of zero is equal to 1. For example, $2^0 = 1$ .

Simplifying Complex Exponents

Now that we have a solid understanding of the properties of exponents, let's apply them to simplify the given expression:

\left[ \left( \frac{5}{3} \right)^3 \div \left( \frac{5}{2} \right)^{-3} \right] \times \left( \frac{3}{2} \right)^{-3}

To simplify this expression, we need to follow the order of operations (PEMDAS):

Evaluate the expressions inside the parentheses: We can start by evaluating the expressions inside the parentheses using the properties of exponents.
Apply the quotient of powers property: We can then apply the quotient of powers property to simplify the expression.
Apply the product of powers property: Finally, we can apply the product of powers property to simplify the expression.

Step 1: Evaluate the expressions inside the parentheses

Let's start by evaluating the expressions inside the parentheses:

\left( \frac{5}{3} \right)^3 = \frac{5^3}{3^3} = \frac{125}{27}

\left( \frac{5}{2} \right)^{-3} = \left( \frac{2}{5} \right)^3 = \frac{2^3}{5^3} = \frac{8}{125}

Step 2: Apply the quotient of powers property

Now that we have evaluated the expressions inside the parentheses, we can apply the quotient of powers property to simplify the expression:

\frac{\frac{125}{27}}{\frac{8}{125}} = \frac{125}{27} \times \frac{125}{8} = \frac{15625}{216}

Step 3: Apply the product of powers property

Finally, we can apply the product of powers property to simplify the expression:

\frac{15625}{216} \times \left( \frac{3}{2} \right)^{-3} = \frac{15625}{216} \times \frac{2^3}{3^3} = \frac{15625 \times 8}{216 \times 27} = \frac{125000}{5832}

Conclusion

In this article, we have explored the world of complex exponents and learned how to simplify expressions involving exponents. We have applied the properties of exponents, including the product of powers, power of a power, quotient of powers, and zero exponent, to simplify the given expression. By following the order of operations and applying these properties, we have arrived at the final simplified expression.

Final Answer

The final simplified expression is:

\frac{125000}{5832}

This expression represents the result of simplifying the given complex exponent expression using the properties of exponents.
