rasionalkan penyebut pecahan pecahaan berikut ini!

[tex] \frac{2}{ \sqrt{7} - \sqrt{3} } \times \frac{ \sqrt{7} + \sqrt{3} }{ \sqrt{7} + \sqrt{3} } = \frac{2( \sqrt{7 } + \sqrt{3} ) }{7 - 3} =
\frac{2( \sqrt{7} + \sqrt{3}) }{4} =
\frac{ \sqrt{7} + \sqrt{3} }{2} [/tex]

2/√7-√3 = 2/√7-√3 x √7+√3/√7+√3
             = 2√7+2√3 / 7- 3
             = 2√7+ 2√3 / 4
             = √7+√3 / 2

semoga membanru :)
