Warm Up Review - Simplify. Write the problem. Write the radicand as prime factors. Simplify. Use good form – alphabetical order (inside and outside of the radical) with radical last. If the power of the variable is an odd number, write the variable with absolute value bars

Simplify. You can have more than one variable in absolute value bars.

10-1B Simplifying Radicals Algebra 1 Glencoe McGraw-Hill Linda Stamper

Simplifying Radicals The simplest form of a radical expression is an expression that has: No perfect square factors other than 1 in the radicand. not simplified No fractions in the radicand. not simplified No radicals in the denominator of a fraction. not simplified

Quotient Property of Radicals zero unnnder the fraction line is unnndefined. In general, write the fraction in lowest terms. Write the numerator as a radical and write the denominator as a radical. Simplify. You may not want to write some fractions in lowest terms.

How does this become five tenths? How does this become one half? Simplifying fractions answer How does this become five tenths? How does this become one half?

Rationalizing the Denominator This is a process used to eliminate a radical from the denominator. Multiply the numerator and the denominator by the radical shown in the denominator. Simplify. The idea is to create a square for the denominator so you can get rid of the radical.

Simplify the expression. Example 3 Example 4 Example 5 Example 6

Simplify the expression. Example 3 Example 4 You cannot reduce because the numerator and the denominator are not both radicals.
