Jika penyebutnya adalah akar, maka harus kita rasionalkan. Caranya adalah dikalikan dengan akar sekawan.

1. [tex] \frac{a}{ \sqrt{b} } \times \frac{ \sqrt{b} }{ \sqrt{b} } = \frac{a \sqrt{b} }{b} [/tex]

2. [tex]\frac{a}{ \sqrt{b} + \sqrt{c} } \times \frac{ \sqrt{b } - \sqrt{c} }{\sqrt{b } - \sqrt{c}} = \frac{a( \sqrt{b} - \sqrt{c}) }{b - c} [/tex]

3. [tex]\frac{a}{ \sqrt{b} - \sqrt{c} } \times \frac{ \sqrt{b } + \sqrt{c} }{\sqrt{b } + \sqrt{c}} = \frac{a( \sqrt{b} + \sqrt{c}) }{b - c} [/tex]

4. [tex]\tiny{\frac{ \sqrt{a} }{ \sqrt[3]{b} + \sqrt[3]{c} } \times \frac{ \sqrt[3]{ {b}^{2} } - \sqrt[3]{b} \times \sqrt[3]{c} + \sqrt[3]{ {c}}^{2} }{\sqrt[3]{ {b}^{2} } - \sqrt[3]{b} \times \sqrt[3]{ c } + \sqrt[3]{ {c}}^{2} } = \frac{a( \sqrt[3]{ {b}^{2} } - \sqrt[3]{b}. \sqrt[3]{c} + \sqrt[3]{ {c}^{2} }) }{b + c} }[/tex]

5. [tex]\tiny{\frac{ \sqrt{a} }{ \sqrt[3]{b} + \sqrt[3]{c} } \times \frac{ \sqrt[3]{ {b}^{2} } + \sqrt[3]{b} \times \sqrt[3]{c} + \sqrt[3]{ {c}}^{2} }{\sqrt[3]{ {b}^{2} } + \sqrt[3]{b} \times \sqrt[3]{ c } + \sqrt[3]{ {c}}^{2} } = \frac{a( \sqrt[3]{ {b}^{2} } + \sqrt[3]{b}. \sqrt[3]{c} + \sqrt[3]{ {c}^{2} } ) }{b - c} }[/tex]
