You probably already knew that 122 = 144, so obviously the square root of 144 must be 12. But my steps above show how you can switch back and forth between the different formats (multiplication …

What are radicals? Radicals (or sometimes referred to as surds) are represented by and are used to calculate the square root or the nth root of numbers and expressions.

In this unit, we review exponent rules and learn about higher-order roots like the cube root (or 3rd root). We'll learn how to calculate these roots and simplify algebraic expressions with radicals.

Nov 16, 2022 · In this section we will define radical notation and relate radicals to rational exponents. We will also give the properties of radicals and some of the common mistakes students often make …

In maths, a radical is the opposite of an exponent that is represented with a symbol '√' also known as root. It can either be a square root or a cube root and the number before the symbol or radical is …

Solving Radical Equations An equation involving radicals is called a radical equation (naturally). To solve it you simply apply our general principle: To solve an equation figure out what bothers you and then …

Radicals are expressed using a radicand (similar to a dividend), a radical symbol, and an index, which is typically denoted as "n." The most common radicals we see are the square root and the cubed root.

Nov 30, 2025 · Learn what radicals are in math, how to simplify them, and when they result in irrational numbers. Includes clear definitions, properties, and worked examples.

Oct 14, 2025 · To simplify n th roots, look for the factors that have a power that is equal to the index n and then apply the product or quotient rule for radicals. Typically, the process is streamlined if you …

Algebra radicals lessons with lots of worked examples and practice problems. Very easy to understand!
