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.

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

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 …
