[tex] \sqrt{10} \times \sqrt{30} \div \sqrt{60 {}^{2} } = \sqrt{10 \times 30 \div 60 {}^{2} } \\ = \sqrt{ \frac{300}{3600} } = \sqrt{ \frac{1}{12} } = \frac{1}{ \sqrt{12} } \\ = \frac{1}{2 \sqrt{3} } = \frac{1 \sqrt{3} }{2 \sqrt{3} \sqrt{3} } = \frac{ \sqrt{3} }{2 \times 3} \\ = \frac{ \sqrt{3} }{6} [/tex]
