Kk kk tlg Jawab Ya :) (pake cara please)

[tex] - 3a {}^{ - 5} b {}^{3} \div 9a {}^{ - 2} b {}^{5} c {}^{ - 7} \\ = - 3 \div 9 \times a {}^{ - 5 - ( - 2)} b {}^{3 - 5}\div c {}^{ - 7} \\= - \frac{3 a {}^{ - 5- (-2) } b {}^{3 - 5} }{9c {}^{ - 7} } \\= - \frac{1 a {}^{ - 5- (-2) } b {}^{3 - 5} }{3c {}^{ - 7} } \\ = - \frac{ a {}^{ - 5 + 2} b {}^{3 - 5} }{3c {}^{ - 7} } \\ = - \frac{a {}^{ - 3} b {}^{ - 2} }{3c { }^{ - 7} } \\ = - \frac{c {}^{7} }{3a {}^{3}b {}^{2} } [/tex]

☛️ Jadi, jawabannya D.
