tolong dijawab yaaa nomor 31 sampai 39 minta bantuannnyaa

[tex]31. \\ {4}^{3} \div {4}^{5} \\ {4}^{3 - 5} \\ {4}^{ - 2} \\ \frac{1}{ {4}^{2} } \\ \frac{1}{16} [/tex]
[tex]32. \\ {3}^{ - 3} \times {3}^{2} \\ {3}^{ - 3 + 2} \\ {3}^{ - 1} \\ \frac{1}{3} [/tex]
[tex]33. \\ 5b {}^{ \frac{3}{7} } \\ \sqrt[7]{5b {}^{3} } [/tex]
[tex]34. \\ (\sqrt[12]{ {b}^{5} } ) {}^{3} \\({ b}^{ \frac{5}{12} } ) {}^{3} \\ ( {b}^{ \frac{5}{4} } ) \\ \sqrt[4]{ {b}^{5} } \\ gak \: ada \: jawabannya. \: salh \: kayaknya[/tex]
