hasil dari 2 akar 6 dikali akar 15 dibagi 2 akar 2

[tex] \frac{2 \sqrt{6} \times \sqrt{15} }{2 \sqrt{2} } \\ = \frac{2 \sqrt{90} }{2 \sqrt{2} } \\ = \frac{2 \sqrt{9 \times 10} }{2 \sqrt{2} } \\ = \frac{2 \times 3 \sqrt{10} }{2 \sqrt{2} } \\ = \frac{6 \sqrt{10} }{2 \sqrt{2} } \\ \\ = \frac{6}{2} \times \sqrt{ \frac{10}{2} } \\ = 3 \sqrt{5} [/tex]
