Soal:
[tex](\frac{1}{81})^{\frac{1}{2}} \times 5\sqrt{32} = ...?[/tex]

Penyelesaian:

[tex](\frac{1}{81})^{\frac{1}{2}} \times 5\sqrt{32} \\ \\ = (\frac{1}{3^{4}})^{\frac{1}{2}} \times 5 \: \times \sqrt{16} \: \times \sqrt{2} \\ \\ = \frac{1^\frac{1}{2}}{3^{4}^\times^\frac{1}{2}} \: \times 5 \: \times 4 \: \times \sqrt{2} \\ \\ = \frac{\sqrt{1}}{3^{2}} \times 20 \: \times \sqrt{2} \\ \\ = \frac{1}{9} \times 20\sqrt{2}[/tex]

Jawaban:

[tex]\frac{1}{9} \times 20\sqrt{2}[/tex]
