hasil dari (8^-1 m^4 n^9)^-3/ (12m^-5 n^-3)

[tex]\frac{ { ({8}^{ - 1} {m}^{4} {n}^{9} )}^{ - 3} }{( {12m}^{ - 5} {n}^{ - 3}) } \\ = \frac{ {8}^{3} {m }^{ - 12} {n }^{ - 27} }{ {12m}^{ - 5} {n}^{ - 3} } \\ = \frac{ {2}^{9} {m}^{ - 12 + 5} {n}^{ - 27 + 3} }{ {2}^{2} \times 3} \\ = \frac{ {2}^{9 - 2} {m}^{ - 7} {n}^{ - 24} }{ 3 } \\ = \frac{ {2}^{7} {m}^{ - 7} {n}^{ - 24} }{3}
