WebTo add square roots, we need like radicals (which have the same radicand, or number under the radical). To multiply or divide square roots, we simplify by factoring out perfect squares (like 4, 9, 16, etc.) from the resulting radicand. In some cases, we may also need to rationalize the denominator. WebRecall that the area of a rectangle equals the length times the width, so to find the width, we must divide the area by the length. √30 20 = √3 2. Now we need to rationalize the denominator. Multiply the top and bottom of the fraction by √2. √3 √2 ⋅ √2 √2 = √6 2. Therefore, the width of the rectangle is √6 2.
