tolong yang bisa kerjain ini, bantu ya! -makasih

1. A
[tex]( \sqrt{3} + \sqrt{5} )( \sqrt{3} + \sqrt{5} ) \\ = 3 + \sqrt{15} + \sqrt{15} + 5 \\ = \: 8 + 2\sqrt{15}[/tex]
2. D
[tex]6 \sqrt{72} \div 12 \sqrt{2} \\ = \: 36 \sqrt{2} \div 12 \sqrt{2} \\ = \: 3[/tex]
3. B
[tex]5 \div 5 + \sqrt{3} \times 5 - \sqrt{3} \div 5 - \sqrt{3} \\ = \: 25 - 5 \sqrt{3} \div 25 - 5 \sqrt{3} + 5 \sqrt{3} - 3 \\ = \: 25 - 5 \sqrt{3} \div 22[/tex]
4. B
[tex]14 - 6 \sqrt{5} \div 4 \\ = \: 7 - 3 \sqrt{5} \div 2[/tex]
5. C
[tex]3 \sqrt{5} + 3 \sqrt{2} \div 3 \\ = \: \sqrt{5} + \sqrt{2} [/tex]
