ada yg tau nmr 2 dan 3? tolong dibantu ya kak :)

Nomor 2 (D)
[tex]2 \sqrt{27} \times \sqrt{32} \div \sqrt{48} \\ = 2 \times 3 \sqrt{3} \times 4 \sqrt{2} \div 4 \sqrt{3} \\ = \frac{6 \sqrt{3} \times 4 \sqrt{2} }{4 \sqrt{3} } \\ = 6 \sqrt{2} [/tex]
Nomor 3 (D)
[tex] \frac{14}{3 + \sqrt{2} } \\ \\ = \frac{14}{3 + \sqrt{2} } \times \frac{3 - \sqrt{2} }{3 - \sqrt{2} } \\ \\ = \frac{14(3 - \sqrt{2}) }{9 - 2} \\ \\ = \frac{14(3 - \sqrt{2} )}{7} \\ \\ = 2(3 - \sqrt{2} ) \\ \\ = 6 - 2 \sqrt{2} [/tex]
