rasionalkan bentuk 4/2-√3

[tex] \frac{4}{2 - \sqrt{3} } X \frac{2 + \sqrt{3} }{2 + \sqrt{3} } = \frac{4(2 + \sqrt{3}) }{4 - 3 } = 4(2 + \sqrt{3}) [/tex]

Merasionalkan Penyebut.

[tex]\displaystyle \frac{4}{2-\sqrt{3}}\\ =\frac{4}{2-\sqrt{3}}~\frac{2+\sqrt{3}}{2+\sqrt{3}}\\ =\frac{8+4\sqrt{3}}{4-3}=4\left ( 2+\sqrt{3} \right )[/tex]
