  1. Chapter 11- Section 4Multiplying Radical Expressions By: Jarrett Dang 3/14/13 Period 2

  2. Objective • Use examples from the textbook to solve show the concepts of Chapter 11.4 • Simplify expressions with radical exponents

  3. Basic Equation of 11.4 √ab= √a ∙ √b

  4. Textbook Pg. 496 #2 √3 × √25 = √3×25 = √3×25 – multiply the radicals together = √125 = √5 × √25 – split up the perfects and the non-perfects = 5√5 – factor out a 25 from the expression

  5. Textbook Pg. 526 #32 √2x² × √5x⁵ = √2x² × 9x⁵ = √2 × 5 × x⁶ × x = √ 10 × x⁶ × x = √x⁶ × √10x - split up the perfects = x³√3x - factor out perfects (x⁶)

  6. Textbook Pg. 496 #42 (√2y)(√3)(√8y) = √2y × √3 × √8y = √6y × √8y - multiply √6y and √3 = √48y² - multiply √6y and √8y = 4y√3 - factor out 16 and y²

  7. THANKS FOR WATCHING!!!!!
