Learn what is 3x x and how to solve it in this comprehensive article. Understand multiplication, the concept of multiplying a variable by a constant, and more.

Multiplication is a fundamental mathematical operation that involves combining two or more numbers to obtain a result called the product. The operation is represented by the symbol “x” and is used extensively in everyday life, including in fields such as science, engineering, finance, and technology. In this article, we will explore what is 3x x and how to solve it.

Definition of multiplication

Multiplication is a mathematical operation that involves adding a number to itself a certain number of times. For instance, 3 x 4 is equivalent to adding 3 four times, which gives us 12. The operation can also be represented using the multiplication symbol “x,” as shown in the example above.

In mathematical terms, the product of two numbers is obtained by multiplying each digit of the first number by each digit of the second number. For example, when multiplying 23 and 5, we multiply 3 by 5, which gives us 15, then multiply 2 by 5, which gives us 10, and finally add the two results to obtain the product, which is 115.

Explanation of the multiplication symbol “x”

The multiplication symbol “x” is a shorthand notation used to represent the multiplication operation. It is widely used in mathematical expressions, equations, and formulas. The symbol is also used in everyday life, such as in product pricing, where it indicates the quantity of items being sold.

The symbol “x” is commonly used to represent multiplication because it is easy to write and recognize, and it does not resemble any other mathematical operation symbols. The symbol is also used to indicate variables in algebraic expressions, where it represents an unknown value that can be determined by solving an equation.

Understanding the multiplication operation and the multiplication symbol “x” is crucial in solving mathematical problems and equations. In the next section, we will explore the concept of multiplying a variable by a constant.

Multiplying a variable by a constant is a fundamental concept in algebraic expressions and equations. In this section, we will explain how to multiply a variable by a constant and the distributive property of multiplication.

Example of multiplying a variable by a constant

Consider the expression 4x, where x is a variable. To multiply 4x by a constant, we simply multiply the constant by the coefficient of the variable, which in this case is 4. For instance, to multiply 4x by 3, we simply multiply 4 by 3, which gives us 12, then write the product next to the variable, which gives us 12x.

Multiplying a variable by a constant is a crucial concept in algebraic expressions and equations, where the variable represents an unknown value that needs to be determined. In the next subsection, we will explain the distributive property of multiplication, which is used extensively in algebraic expressions.

Solving for 3x x

In this section, we will explain how to solve for 3x x, which is a multiplication of a variable by a constant.

Step-by-step guide on solving 3x x

To solve for 3x x, we use the distributive property of multiplication, which states that the product of a number and a sum is equal to the sum of the products of the number and each term in the sum. In other words, a(b + c) = ab + ac.

Using the distributive property, we can rewrite 3x x as 3 x x, which is equivalent to 3x². Therefore, 3x x is the same as 3 times x squared.

Example of solving 3x x

Suppose we want to solve the equation 3x x = 24. We can use the distributive property to rewrite the equation as 3x² = 24. To solve for x, we divide both sides of the equation by 3, which gives us x² = 8. Finally, we take the square root of both sides of the equation to obtain the two possible values of x, which are x = √8 and x = -√8.

Therefore, the solutions to the equation 3x x = 24 are x = √8 and x = -√8.

Solving for 3x x is a crucial concept in algebraic expressions and equations, where the variable represents an unknown value that needs to be determined. In the next section, we will explore the practical applications of multiplying.

Practical Applications of Multiplying

Multiplication has many practical applications in everyday life and in various fields, including science, engineering, finance, and technology. In this section, we will explore some real-life examples of multiplication and its importance in various fields.

Real-life examples of multiplication

One of the most common examples of multiplication in everyday life is when we calculate the total cost of buying multiple items of the same product. For instance, if a product costs $2 and we want to buy 5 units, we multiply the cost by the quantity, which gives us a total cost of $10.

Multiplication is also used in cooking, where we need to adjust the quantities of ingredients according to the number of servings. For example, if a recipe calls for 2 cups of flour to make 4 servings, we can use multiplication to determine the amount of flour needed to make 8 or 12 servings.
