1) Main Idea: A radical expression is an expression that contains one or more radicals. Write radical or radicand in each blank. sign: Means "square root" - square root of b Think: What times itself equals b?2) Main Idea: Every positive number has two square roots: the principal square root and its opposite. Fill in the blanks to complete the property. Then use it to find the value of each expression. Principal Square Root For any number a and nonnegative number b, 149 - ( 12. 1) = _ VO =3) Main Idea: You can use the product property of radicals to simplify radical expressions. Fill in the blanks to complete the property. Then use it to find each product. Product Property of Radicals For any nonnegative numbers a and b, 3. 17 -4} Fill in the blanks to complete the steps. Then use them to simplify the radical. How in rinualll)r individual Handled: Steps Example: 425 'I. Faster out any squares from the radicand. 2. Split the radical into a of two radicals. 3. Simplify. 5) Main Idea: You can use the quotient property of radicals to simplify radical expressions. Fill in the blanks to complete the property. Then use it to find each quotient. Quotient Property of Radicals For any nonnegative number a and positive number b, b 306) Fill in the blanks to complete the steps. Then use them to simplify the radical. How to Simplify the Square Root of a Fraction Steps Example: 10 19 1. Split the radical into a of two radicals. 2. Simplify the numerator and 7) Main Idea: To simplify some radical expressions, you need to use all the properties of radicals. Simplify each expression. 15 21 1/20
