Introduction

In mathematics, simplifying expressions is a crucial skill that helps us to evaluate and manipulate mathematical statements more efficiently. One of the key concepts in simplifying expressions is the idea of single power, which refers to the process of combining multiple instances of the same base raised to different exponents into a single instance of the base raised to a single exponent. In this article, we will explore how to rewrite expressions as single powers, using examples and step-by-step explanations to illustrate the concept.

Understanding Single Power

Single power is a fundamental concept in algebra that allows us to simplify expressions by combining multiple instances of the same base raised to different exponents. The key idea behind single power is that when we have multiple instances of the same base raised to different exponents, we can combine them into a single instance of the base raised to a single exponent. This is achieved by adding the exponents together.

Example 1: Simplifying a Fraction

Let's consider the expression $\frac{6^3}{6^3}$ . At first glance, this expression may seem complex, but it can be simplified using the concept of single power.

Step 1: Identify the base and exponents

In this expression, the base is 6, and the exponents are 3 and 3.

Step 2: Add the exponents

Since the exponents are the same, we can add them together: $3 + 3 = 6$ .

Step 3: Rewrite the expression as a single power

Using the result from step 2, we can rewrite the expression as a single power: $6^6$ .

Example 2: Simplifying an Expression with Multiple Terms

Let's consider the expression $2^2+2^1+2^0$ . This expression consists of multiple terms, each with a different exponent. We can simplify this expression using the concept of single power.

Step 1: Identify the base and exponents

In this expression, the base is 2, and the exponents are 2, 1, and 0.

Step 2: Add the exponents

Since the base is the same, we can add the exponents together: $2 + 1 + 0 = 3$ .

Step 3: Rewrite the expression as a single power

Using the result from step 2, we can rewrite the expression as a single power: $2^3$ .

Introduction

In our previous article, we explored the concept of single power and how it can be used to simplify complex mathematical expressions. In this article, we will answer some of the most frequently asked questions about single power, providing additional insights and examples to help you master this essential skill.

Q: What is single power?

A: Single power is a mathematical concept that allows us to combine multiple instances of the same base raised to different exponents into a single instance of the base raised to a single exponent.

Q: How do I identify the base and exponents in an expression?

A: To identify the base and exponents in an expression, look for the numbers and variables that are raised to powers. The base is the number or variable that is being raised to a power, and the exponents are the numbers that are being added to the base.

Q: What is the order of operations when simplifying expressions using single power?

A: When simplifying expressions using single power, follow the order of operations (PEMDAS):

Parentheses: Evaluate any expressions inside parentheses first.
Exponents: Evaluate any exponents next.
