Penjelasan dengan langkah-langkah:
[tex] = \frac{2 \sqrt{5} }{ \sqrt{72} } \times \frac{ \sqrt{72} }{ \sqrt{72} } [/tex]
[tex] = \frac{2 \sqrt{360} }{72} [/tex]
[tex] = \frac{2 \sqrt{36 \times 10} }{72} [/tex]
[tex] = \frac{2 \times 6 \sqrt{10} }{72} [/tex]
[tex] = \frac{12 \sqrt{10} }{72} [/tex]
[tex] = \frac{1 \sqrt{10} }{6} [/tex]
[tex] = \frac{1}{6} \sqrt{10} [/tex]
