Simplifying expressions with roots
WebbSimplifying square roots with variables Example Let's simplify \sqrt {54x^7} 54x7 by removing all perfect squares from inside the square root. First, we factor 54 54: 54=3\cdot 3\cdot 3\cdot 2=3^2\cdot 6 54 = 3 ⋅ 3 ⋅ 3 ⋅ 2 = 32 ⋅ 6 Then, we find the greatest perfect … - [Instructor] Let's get some practice.
