WebAug 26, 2024 · First, you can factor it out to get √ (9 x 5). Then, you can pull out a "3" from the perfect square, "9," and make it the coefficient of the radical. So, √ (45) = 3√5. [6] X Research source. Now, just add up the coefficients of the two terms with matching radicands to get your answer. 3√5 + 4√5 = 7√5. 2. Do Example 2. WebSplit the fraction into 2 radicals. √ (1/200) = √ (1)/√ (200) Simplify both square roots. √ (1) = 1 √ (200) = √ (10*10*2) = 10√ (2) So, your fraction becomes: 1/ [10√ (2)] Next, a simplified radical will have no radicals in the denominator. So you need to rationalize the denominator. 1/ [10√ (2)] = 1/ [10√ (2)] * √ (2)/√ (2) = √ (2)/ [10√ (4)]
