Since 28 = 4 \u00d7 7 and \u221a4 = 2, we get \u221a28 = 2\u221a7. To simplify a surd, split the number under the root into a perfect-square factor and the remaining factor. Take the square root of the perfect square outside the radical. The expression is simplified when no square factor greater than 1 remains under the root.
