[tex]\boxed{=\frac{10\sqrt{2}-\sqrt{30}}{10}}[/tex]
Penjelasan :
[tex]\displaystyle\frac{2\sqrt{5}-\sqrt{3}}{\sqrt{10}}\\\\=\frac{(2\sqrt{5}-\sqrt{3})\times\sqrt{10}}{\sqrt{10}\times\sqrt{10}}\\\\=\frac{(2\sqrt{5}\times\sqrt{10})-(\sqrt{3}\times\sqrt{10})}{10}\\\\=\frac{(2\sqrt{5}\times\sqrt{5}\times\sqrt{2})-\sqrt{30}}{10}\\\\=\frac{(2\times5\times\sqrt{2})-\sqrt{30}}{10}\\\\=\bf\frac{10\sqrt{2}-\sqrt{30}}{10}[/tex]

6Penjelasan dengan langkah-langkah:
kemungkinan maksud soal :
[tex] = \frac{ 2 \sqrt{5} - \sqrt{3} }{ \sqrt{10} } \times \frac{ \sqrt{10} }{ \sqrt{10} } [/tex]
[tex] = \frac{2 \sqrt{50} - \sqrt{30} }{ \sqrt{100} } [/tex]
[tex] = \frac{2 \sqrt{25.2} - \sqrt{30} }{10} [/tex]
[tex] = \frac{2 \times 5 \sqrt{2} - \sqrt{30} }{10} [/tex]
[tex] = \frac{10 \sqrt{2} - \sqrt{30} }{10} [/tex]
