## 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.

Remember – there are two roots for every positive number.

The √ sign referring to the positive root unless there
