1. Nilai dari [tex]5 \sqrt{96} + \sqrt{80} [/tex] 2. (soalnya yg di foto)

[tex]1).5 \sqrt{96 } + \sqrt{8} \\ =5 \times 4 \sqrt{6} + 2 \sqrt{2} \\ = 20 \sqrt{6} + 2 \sqrt{2} [/tex]
[tex]2). \frac{ \sqrt[4]{x {}^{3} } }{ \sqrt{x {}^{6} } } \\ = \frac{x {}^{ \frac{3}{4} } }{ {x}^{ \frac{6}{2} } } \\ = {x}^{ \frac{3}{4} - \frac{6}{2} } \\ = {x}^{ - \frac{9 }{4} } \\ = \frac{1}{ {x}^{ \frac{9}{4} } } \\ = \frac{1}{ \sqrt[4]{ {x}^{9} } } [/tex]
semoga membantu...
