WebbSurds can be subtracted by subtracting the coefficient of their roots. c\sqrt {a} - b\sqrt {a} = (c - b) \sqrt {a} c a − b a = (c − b) a, where c and b are the coefficient of the root. Please … Webb1. For applying rationalization of surds on a surd expression, it must be a two-term surd of the form (√a ± √b). For example, 2 − √3 or √19 + 3√2 can be rationalized, but 2 + √3 + √5 … Webb(ii) Simplest form of a surd : A surd is said to be in simplest form, when it is expressed as the product of a rational factor and an irrational factor. In this form the surd has (a) the smallest possible index of the radical sign. (b) no fraction under the radical sign. (c) no factor is of the form an, where a is a positive integer under index n. ontario family law act section 6
