Simplifying numerical radical expressions
In this tutorial you will simplify numerical expressions with radicals by removing all factors that are perfect squares from inside the radical.
Simplify numerical radical terms by removing all factors that are perfect squares from inside the radical.
Sal shows how to group like terms to add and simplify radical terms, by simplifying the expression √(2x^2)+4√8+3√(2x^2)+√8.
Sal shows how to group like terms to subtract and simplify radical terms, by simplifying the expression 4∜(81x^5)-2∜(81x^5)-√(x^3).
Practice simplifying radical expressions with two terms.
Sal shows how to manipulate expressions like 1/√2 and 12/(2-√5) so there's no radical in the denominator. This is called "rationalizing the denominator."
Sal shows how to rationalize the denominator of the expression (16+2x^2)/(√8).
Practice simplifying expressions with multiple radical terms combined by addition, subtraction, multiplication, and/or division.
