1. Find the exact value. 1.) √49 2.) - √144 3. Use a calculator to approximate the value of √(82/16) to the nearest tenth.

2. Algebra II

3. Solve quadratic equations by finding square roots.

4. Square root – a number r if r 2 = s (another number) Radical – the expression √s, the symbol √ is a radical sign Radicand – The number underneath the radical sign.

5. Product Property √ab = √a * √b Quotient Property √(a/b) = √a / √b

6. Simplify the expression. A.) √75 B.) √7 * √35 C.) √(100/169) D.) √(11/144)

7. Rationalizing the denominator means to eliminate the radical sign from the denominator. Form of the denominatorMultiply the numerator and denominator by: √b a + √ba - √b a + √b
