Question

помогите пожалуйста. ​

Answer 1

$1) \: \: \: ( { {a}^{2} {b}^{ - 1} })^{- 1} = \frac{b}{ {a}^{2} }$

$2) \: \: \: (2a {}^{ - 3} ) {}^{2} = 4 {a}^{ - 6} = \frac{4}{ {a}^{6} }$

$3) \: \: \: ( \frac{1}{2} {b}^{4} ) {}^{ - 2} = ({ \frac{1}{2} })^{ - 2} {b}^{ - 8} = \frac{4}{ {b}^{8} }$

$4) \: \: \: (\frac{1}{3} {x}^{ - 2} {y}^{ 3} ) {}^{ - 2} = \frac{9 {x}^{4} }{ {y}^{6} }$

$5) \: \: \: (0.1 {m}^{5} {n}^{ - 2} ) {}^{ - 2} = 100 \frac{ {n}^{4} }{ {m}^{10} }$

$6) \: \: \: (0.2 {p}^{ - 3} n) {}^{ - 2} = \frac{100 {p}^{6} }{4 {n}^{2} } = \frac{25 {p}^{6} }{ {n}^{2} }$
