Chapter 1: Problem 83
Evaluate. What is the cube of \(6 ?\)
Short Answer
Expert verified
The cube of 6 is 216.
Step by step solution
01
Understanding the Term 'Cube'
When we say 'the cube of a number', we mean that we multiply the number by itself twice. In other words, the cube of a number \(x\) is given by \(x * x * x\). So, to find the cube of 6, we need to multiply 6 by itself twice.
02
Calculating the Cube of 6
To calculate the cube of 6, or \(6^3\), we multiply 6 by 6, and then multiply the result by 6 again. So, \(6^3 = 6 * 6 * 6 = 216\).

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Powers and Exponents
In mathematics, **powers and exponents** are ways to express repeated multiplication of a number by itself. When you have a number, like 6, raised to a power such as 3, it is written as \(6^3\). Here, 6 is called the base, and 3 is the exponent.
- The base is the number you multiply.
- The exponent tells you how many times to multiply the base by itself.
Multiplication
**Multiplication** is one of the basic operations in arithmetic. It's a quick way to add up several instances of the same number. For example, when we multiply 6 by 3, it is the same as adding 6 three times:
6 + 6 + 6. For the cube of a number like in this problem, multiplication allows us to find how many groups of the number are in a larger total, without having to add them one at a time.
- First, multiply 6 by 6, which gives you 36.
- Second, multiply the result, 36, by another 6.
Basic Arithmetic
**Basic arithmetic** involves the fundamental operations of addition, subtraction, multiplication, and division. Among these, multiplication is pivotal when dealing with powers and exponents. It's important to have a solid understanding of arithmetic to make calculations faster and more accurate.
- Track progress as you integrate each step, especially in sequences like cubing a number.
- Cross-check results after each multiplication to confirm accuracy.
Exponents in Prealgebra
**Exponents in prealgebra** introduce the concept of raised powers before tackling more advanced mathematical topics. This is often the first stage where students learn the significance of multiplying a number by itself multiple times. Exponents simplify expressions and equations, making them manageable.
- Prealgebra exponents mainly revolve around small, easily understandable numbers.
- Understanding how numbers increase rapidly with exponentiation forms a foundation for later math studies.
