Multiplication Property of Square Roots: 1) For a ≥ 0, b ≥ 0, 2) For a ≥ 0, b ≥ 0, Ex: What is the simplest form of: 1) 2) 3)
SOLUTION: To simplify we must provide the prime factors and perfect squares of each integer given. 1) 9 2) 6 2x 3)
REAL-WORLD: A rectangular door in a museum is three times as tall as it is wide. What is a simplified expression for the maximum length of a painting that fits through the door?
SOLUTION: From the given sketch, we have the following: c = ? a = w and b = 3w Using Pythagorean Theorem: a2+b2 = c2 (w)2+(3w)2 = c2 w2+9w2 = c2 10w2 = c2 c = c = -w or +w Length cannot be negative thus: c = w
