  • How to simplify square roots (review) (article) | Khan Academy
    Learn how to rewrite square roots (and expressions containing them) so there's no perfect square within the square root For example, rewrite √75 as 5⋅√3 Simplifying square roots
  • Khan Academy
    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
  • Simplifying cube root expressions - Khan Academy
    They include: square roots, cube roots, 4th roots, 5th roots, 6th roots, etc If there is a number on the little arm of the radical, it is telling you the root that you need If no number is on the arm, then the radical is a square root
  • Simplifying square roots (variables) - Khan Academy
    Taking the square root of something and multiplying that times the square root of something else is the same thing as just taking the square root of 5x So all of this simplified down to 30 times the absolute value of x times the principal root of 5x

  • Square roots – Khan Academy Help Center
    If you haven't already, Khan Academy has some content on simplifying square roots with variables that should help you out There are also exercises that give you the explanation step by step if you need help
  • Simplifying square-root expressions: no variables - Khan Academy
    When square roots have the same value inside the radical, we can combine like terms First we simplify the radical expressions by removing all factors that are perfect squares from inside the radicals Then we can see whether we can combine terms or not If there is only one term, there is nothing to combine
