Nomor 1
[tex] \sqrt{5} \times \sqrt{3} \\ = \sqrt{5 \times 3} \\ = \sqrt{15} [/tex]
[tex] \\ [/tex]
Nomor 2
[tex]2 \sqrt{13} \times \sqrt{9} \\ = 2 \sqrt{13} \times 3 \\ = (2 \times 3) \sqrt{13} \\ = 6 \sqrt{13} [/tex]
[tex] \\ [/tex]
Nomor 3
[tex]8 \sqrt{3} \times 24 \sqrt{12} \\ = (8 \times 24) \times \sqrt{3 \times 12} \\ = 192 \times \sqrt{36} \\= 192 \times 6 \\ = 1.152[/tex]
[tex] \\ [/tex]
Nomor 4
[tex] \sqrt{6} (5 + \sqrt{12} ) \\ = \sqrt{6} \times 5 + \sqrt{6 \times 12} \\ = 5 \sqrt{6} + \sqrt{72} \\ = 5 \sqrt{6} + \sqrt{36 \times 2} \\ = 5 \sqrt{6} + 6 \sqrt{2} [/tex]
[tex] \\ [/tex]
Nomor 5
[tex] \frac{ \sqrt{16} }{ \sqrt{2} } \\ \\ = \sqrt{16 \div 2} \\ \\ = \sqrt{8} \\ \\ = \sqrt{4 \times 2} \\ \\ = 2 \sqrt{2} [/tex]
Nomor 6
[tex] \frac{ \sqrt{20} }{2 \sqrt{5} } = \frac{ \sqrt{4 \times 5} }{2 \sqrt{5} } \\ \\ = \frac{2 \sqrt{5} }{2 \sqrt{5} } \\ \\ = 1[/tex]
[tex] \\ [/tex]
Nomor 7
[tex] \frac{70 \sqrt{8} }{5 \sqrt{2} } \\ \\ = \frac{70}{5} \times \frac{ \sqrt{8} }{ \sqrt{2} } \\ \\ = 14 \times \sqrt{4} \\ \\ = 14 \times 2 \\ \\ = 28[/tex]
[tex] \\ [/tex]
Nomor 8
[tex] \frac{ \sqrt{24} }{ \sqrt{45} } \\ \\ = \frac{ \sqrt{4 \times 6}}{ \sqrt{9 \times 5}} \\ \\ = \frac{2 \sqrt{6} }{3 \sqrt{5} } \\ \\ = \frac{2 \sqrt{6} }{3 \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } \\ \\ = \frac{2 \sqrt{30} }{3 \times 5} \\ \\ = \frac{2 \sqrt{30} }{15} [/tex]
[tex] \\ [/tex]
Nomor 9
[tex] \frac{ \sqrt{9} }{ \sqrt{2} } = \frac{ 3 }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ \\ = \frac{3 \sqrt{2} }{2} [/tex]
