What is an algebraic expression? Give an example with your explanation.

Short Answer

Expert verified
An algebraic expression is a mathematical phrase that combines variables, constants, and operations to represent a particular relation. For instance, the expression \(3x+4y-5\) is an algebraic expression combining variables \(x\) and \(y\), constants \(3, 4,\) and \(-5\), and the operations of addition and multiplication.

Step by step solution

01

Definition of an Algebraic Expression

An algebraic expression is a mathematical statement that consists of variables, numbers, and operations (such as addition, subtraction, multiplication, and division). Expressions are used to represent problems in mathematical terms and have no equal (=) sign.
02

Components of an Algebraic Expression

There are three main components in an algebraic expression. Variables (such as x, y, z) that represent unknown values, Constants (like 1, 2, 3, etc.) which are fixed values that do not change, and Operations which are mathematical procedures like addition (+), subtraction (-), multiplication (*) and division (/), and can also include powers.
03

Example of an Algebraic Expression

Here is an example of an algebraic expression: \[3x+4y-5\]. In this expression, x and y are the variables, 3, 4, and -5 are constants, and the operations are addition and multiplication.

Find all integers b so that the trinomial can be factored. $$ x^{2}+4 x+b $$

Use Einstein's special-relativity equation $$R_{a}=R_{f} \sqrt{1-\left(\frac{v}{c}\right)^{2}}$$ described in the Blitzer Bonus on page \(47,\) to solve this exercise. You are moving at \(90 \%\) of the speed of light. Substitute \(0.9 c\) for \(v,\) your velocity, in the equation. What is your aging rate, correct to two decimal places, relative to a friend on Earth? If you are gone for 44 weeks, approximately how many weeks have passed for your friend?

Simplify by reducing the index of the radical. $$\sqrt[9]{x^{6} y^{3}}$$

Read the Blitzer Bonus on page \(47 .\) The future is now: You have the opportunity to explore the cosmos in a starship traveling near the speed of light. The experience will enable you to understand the mysteries of the universe in deeply personal ways, transporting you to unimagined levels of knowing and being. The downside: You return from your two-year journey to a futuristic world in which friends and loved ones are long gone. Do you explore space or stay here on Earth? What are the reasons for your choice?
