These surds may be monomials or binomials involving square roots, in simple examples. There are wide extensions to the technique. == Rationalisation of a monomial square root and cube root == For the fundamental technique, the numerator and denominator must be multiplied by the same factor. Example 1: : $\backslash frac$: : $\backslash frac\}$ The square root disappears from the denominator, because it is squared: : $\backslash frac\}\; =\; \backslash frac$ This gives the result, after simplification: : $\backslash frac\}$ Example 2: : $\backslash frac^2$: : $\backslash frac^2\}\; =\; \backslash frac$ The cube root disappears from the denominator, because it is cubed: : $\backslash frac\; =\; \backslash frac$ This gives the result, after simplification: : $\backslash frac$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rationalisation (mathematics)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
