### Grade 7 - Mathematics4.12 The Square Root of a Monomial

 A monomial which can be written as the square of another monomial is called a "perfect" or "exact" square. If a monomial is a perfect square, then it can be expressed as a product of two equal factors. In such a case each of the equal factors is called a "Square root" of the given monomial. Example:Find the square root of √(18x2y4). Solution: 9xy2 * 9xy2 Therefore the √(18x2y4) = 9xy2. Directions: Solve the following square root problems and show your work. Also write at least ten examples of your own.
