tolong kerjakan yang dibulatkan ya

2.
[tex] = {81}^{ \frac{1}{2} } + {27}^{ \frac{2}{3} } - {2}^{3} \\ = \sqrt{81} + \sqrt[3]{ {27}^{2} } - {2}^{3} \\ = 9 + 9 - 8 \\ = 10[/tex]
Jawaban A.

3.
[tex] = \frac{12 \sqrt{8} }{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } \\ = \frac{12 \sqrt{16 \times 3} }{6} \\ = \frac{48 \sqrt{3} }{6} \\ = 8 \sqrt{3} [/tex]
Jawaban C

Ini nomor 2 yahhhhhhhhh
