merasionalkan bentuk akar 7 kurang akar 3 bagi akar 7 tambah akar 3

[tex] \frac{ \sqrt{7} - \sqrt{3} }{ \sqrt{7} + \sqrt{3} } \times \frac{ \sqrt{7} - \sqrt{3} }{ \sqrt{7} - \sqrt{3} } = \frac{( \sqrt{7} - \sqrt{3}) ( \sqrt{7} - \sqrt{3} ) }{( \sqrt{7 } + \sqrt{3} )( \sqrt{7} - \sqrt{3} } = \frac{7 - 2 \sqrt{21} + 3 }{7 - 3} = \frac{10 - 2 \sqrt{21} }{4} = \frac{5 - \sqrt{21} }{2} [/tex]
yap begiru kira kira jawabannya


maaf jika salah ya
