Question

пожалуйста помогите!!!!​

Answer 1

$1) \frac{ {m}^{6} ( {m}^{ - 2 }) {}^{5} }{ {m}^{ - 3} {m}^{7} } = \frac{ { m}^{6} \times {m}^{ - 10} }{ {m}^{ - 3 + 7} } = \frac{ {m}^{6 - 10} }{ {m}^{4} } = \frac{ {m}^{ - 2} }{ {m}^{4} } = \frac{1}{ {m}^{6} } = \frac{1}{(0.5) {}^{6} } = {2}^{6} = 64$

$2)\frac{ {x}^{ - 3} {y}^{ - 5}( {x}^{2}y) {}^{ - 1} }{( {x}^{ - 3} ) {}^{2} {y}^{ - 4} } = \frac{ {x}^{3} {y}^{ - 5} {x}^{ - 2}y {}^{ - 1} }{ {x}^{ - 6} {y}^{ - 4} } = \frac{ {x}^{3 - 2} {y}^{ - 5 - 1} }{ {x}^{ - 6}y {}^{ - 4} } = \frac{x \times y {}^{ - 6} }{ {x}^{ - 6} \times {y}^{ - 4} } = \frac{ {x}^{7} }{ {y}^{2} } = \frac{ {5}^{7} }{ {15}^{2} }$
