Question

Write with a single exponent. $$ \frac{a^{x}}{b^{x}} $$

Short answer

Question: Write the expression $\frac{a^{x}}{b^{x}}$ with a single exponent. Answer: The simplified expression with a single exponent is $(\frac{a}{b})^{x}$.

Step-by-step solution

Apply the Quotient Property of Exponents

We will use the quotient property of exponents to simplify the given expression. The quotient property states that for any real numbers a, b (b≠0), and x: $$ \frac{a^{x}}{b^{x}} = (\frac{a}{b})^{x} $$ We will apply this property to the given expression.

Simplify the given expression

Using the quotient property of exponents, the given expression becomes: $$ \frac{a^{x}}{b^{x}} = (\frac{a}{b})^{x} $$ The expression is now written with a single exponent. The final simplified expression is: $$ (\frac{a}{b})^{x} $$

Key concepts

Exponent Rules

Exponent rules are fundamental tools in algebra that help us simplify expressions involving powers. These rules govern how we deal with exponents when multiplying, dividing, or raising them to a power.

One of the most important exponent rules is the Quotient Property of Exponents. This property states that when you divide two terms with the same base, you subtract the exponents. For instance, when you have \( \frac{a^m}{a^n} \), it simplifies to \( a^{m-n} \). However, it's important to note that the Quotient Property can also be rearranged as seen in our original exercise: when you have different bases but the same exponent, like \( \frac{a^x}{b^x} \), you can combine them as \( \left(\frac{a}{b}\right)^x \).

Remember that exponent rules only apply when the bases are the same unless the property specifically indicates otherwise to efficiently manage expressions.

Algebraic Expressions

Algebraic expressions are a combination of numbers, variables, and operations. They can represent almost anything you can calculate, from simple arithmetic to complex functions.

At the heart of algebraic expressions are variables, which are symbols (often letters) representing unknown or changeable values. For example, in \( a^x \), "a" is the base that can be any real number, while "x" is the exponent. Every part of the expression plays a clear role that contributes to the value of the entire expression.

When dealing with expressions like \( \frac{a^x}{b^x} \), understanding each component's role can simplify your work. Here, the expression involves division and powers, which the Quotient Property helps to combine efficiently. Both "a" and "b" can affect the result, so knowing each value is essential for evaluation.

Simplification Techniques

Simplification is the process of making an expression easier to understand or work with while keeping its value intact. Efficient simplification techniques can transform complex expressions into more manageable forms.

One primary technique involves using the rules of exponents to combine or reduce expressions. In our exercise, we utilized the Quotient Property of Exponents, allowing us to convert \( \frac{a^x}{b^x} \) into \( \left(\frac{a}{b}\right)^x \). This method draws on known properties to reduce the complexity of the expression, turning it from a fraction involving two exponentiated terms into a single term.

Moreover, always look for ways to factor, combine like terms, or cancel out terms to achieve the simplest form. Simplification can not only make expressions neater but also faster to solve and easier to interpret, especially for larger problems or equations in algebra.
