Exercise 41 Page 623

We want to simplify a radical expression. To do so we will assume that a>0, otherwise the given expression would not be defined. 11sqrt(49a^5/4a^3)Let's recall the Multiplication Property of Square Roots and the Division Property of Square Roots. sqrt(ab)&=sqrt(a) * sqrt(b), for a≥ 0,b≥ 0 [0.4em] sqrt(a/b)&=sqrt(a)/sqrt(b), for a≥ 0,b> 0 Let's use these properties for our expression.
