rasionalkan penyebut dari pecahan berikut :

1. 5 / 2√10
2. √9 / 2√3
3. 4 / √7 + √3
4. 6 / 3 - 2 √3
5. √6 / 2 √3 + √2

Bantu jawab, jangan asal - asalan, terimakasih

Penjelasan dengan langkah-langkah:

$\frac{5}{2 \sqrt{10} } \\ \frac{5}{2 \sqrt{10}} \times \frac{ \sqrt{10} }{ \sqrt{10} } \\ \frac{5 \sqrt{10} }{20} \\ \frac{1}{4} \sqrt{10}$

$\frac{ \sqrt{9} }{2 \sqrt{3} } \\ \frac{3}{2 \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } \\ \frac{3 \sqrt{3} }{6} \\ \frac{1}{2} \sqrt{3}$

$\frac{4}{ \sqrt{7} + \sqrt{3} } \\ \frac{4}{ \sqrt{7} + \sqrt{3} } \times \frac{ \sqrt{7} - \sqrt{3} }{ \sqrt{7} - \sqrt{3} } \\ \frac{4( \sqrt{7} - \sqrt{3}) }{7 - 3} \\ \frac{4( \sqrt{7} - \sqrt{3} )}{ 4 } \\ \sqrt{7} - \sqrt{3}$

$\frac{6}{3 - 2 \sqrt{3} } \\ \frac{6}{3 - 2 \sqrt{3} } \times \frac{3 + 2 \sqrt{3} }{3 + 2 \sqrt{3} } \\ \frac{6(3 + 2 \sqrt{3} )}{9 - 12} \\ \frac{6(3 + 2 \sqrt{3)} }{ - 3} \\ - 2(3 + 2 \sqrt{3)} \\ - 6 - 4 \sqrt{3}$

$\frac{ \sqrt{6} }{2 \sqrt{3} + \sqrt{2} } \\ \frac{ \sqrt{6} }{2 \sqrt{3} + \sqrt{2} } \times \frac{2 \sqrt{3} - \sqrt{2} }{2 \sqrt{3} - \sqrt{2} } \\ \frac{ \sqrt{6} (2 \sqrt{3} - \sqrt{2} ) }{12 - 2} \\ \frac{2 \sqrt{18} - \sqrt{12} }{10} \\ \frac{6 \sqrt{2} - 2 \sqrt{3} }{10} \\ \frac{3 \sqrt{2} - \sqrt{3} }{5}$
