### Lesson 11-4 Irrational Square Roots

Objective : To simplify radicals and to find decimal approximations of irrational square roots.

Irrational Numbers
• Irrational numbers are real numbers that cannot be expressed in the form a/b when a and b are integers.
• Π is an irrational number
• Nonterminating, nonrepeating decimals are irrational numbers
Property of Completeness
• Every decimal number represents a real number, and every real number can be represented by a decimal.
