Объяснение:
[tex]( { \frac{ {a}^{ - 5} \times {b}^{8} }{ {x}^{9} \times {y}^{ - 12} } })^{ - 8} = ({ \frac{ {b}^{8} \times {y}^{12} }{ {x}^{9} \times {a}^{5} } })^{ - 8} = \frac{ {x}^{8 \times 9} \times {a}^{5 \times 8} }{ {b}^{8 \times 8} \times {y}^{12 \times 8} } = \frac{ {x}^{72} \times {a}^{40} }{ {b}^{64} \times {y}^{96} } [/tex]
Ответ:
[tex]\frac{a^{15} x^{27} }{y^{36} b^{24} }[/tex]
[tex]\frac{a^{(-5)(-3)} b^{8(-3)} }{x^{9(-3)} y^{(-12)(-3)} } =\frac{a^{15} b^{-24} }{x^{-27} y^{36} } =\frac{a^{15} }{y^{36} }\frac{1}{b^{24}}\frac{x^{27} }{1} } =\frac{a^{15} x^{27} }{y^{36} b^{24} }[/tex]
