2)![-\dfrac{5}{\sqrt{3} } = -\dfrac{5 \cdot \sqrt{3} }{3}](/tpl/images/1392/6496/c93a4.png)
3)![\dfrac{\sqrt{2} + \sqrt{5} }{\sqrt{10} } =\dfrac{\sqrt{5} }{5} + \dfrac{ \sqrt{2} }{2}](/tpl/images/1392/6496/da8e1.png)
4)![\dfrac{3 + \sqrt{2} }{\sqrt{3} } \times \dfrac{\sqrt{3} }{\sqrt{3} } = \sqrt{3} + \dfrac{\sqrt{6} }{3}](/tpl/images/1392/6496/3d5b0.png)
5)![\dfrac{\sqrt{3} }{\sqrt{5} + \sqrt{2} }= \dfrac{\sqrt{15} - \sqrt{6} }{3}](/tpl/images/1392/6496/46e17.png)
Step-by-step explanation:
The rationalization of the denominator of the surds are found as follows;
