mohon bantuannya gays:

[tex]5. \: {32}^{ \frac{2}{3} \times \frac{3}{5} } = {32}^{ \frac{2}{5} } = {2}^{5 \times \frac{2}{5} } = {2}^{2} = 4[/tex]
[tex]6. \: 4 \sqrt{2 \times 9} \div 3 \sqrt{3 \times 4} \\ = 4 \times 3 \sqrt{2} \div 3 \times 2 \sqrt{3} \\ = 12 \sqrt{2} \div 6 \sqrt{3} = \frac{12 \sqrt{2} }{6 \sqrt{3} } \\ = \frac{2 \sqrt{2} }{ \sqrt{3} } [/tex]
[tex] \frac{2 \sqrt{2} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{2 \sqrt{3 \times 2 \times 3} }{3} = \frac{2 \times 3 \sqrt{2} }{3} = \frac{6 \sqrt{2} }{3} = 2 \sqrt{2} [/tex]
