por favor ayuden doy corona ala mejor respuesta

Answer 1

Respuesta:

$1. \: ( \frac{5x }{7y}) {}^{ - 2} = \frac{49y {}^{2} }{25x {}^{2} }$

$2. \: ( \frac{1}{5} ) ^{1} = \frac{1}{5}$

$3. \: ( - \frac{2}{5})^{10} \times( - \frac{2}{5})^{ - 7} \: = - \frac{8}{125}$

$4. \: (\frac{2}{ \alpha }^{0}) = \frac{1}{ \alpha }$

$5. \: ( \frac{4}{3x})^{8} \div ( \frac{4}{3x} ) {}^{4} = \frac{256}{81x {}^{4} }$

$6. \: (3n) {}^{2} = 9n {}^{2}$

$7. \: ( \frac{1}{2} \times \frac{7}{3}) {}^{2} = \frac{49}{36}$

$8. \: ( ( \frac{2}{3} {}^{3} ) {}^{2} ) = \frac{64}{729}$

$9. \: (( \frac{3}{4}) {}^{3} \times ( \frac{3}{4}) {}^{2} ) {}^{4} \div (( \frac{3}{4}) {}^{7} ) {}^{3} = \frac{4}{3}$

Me das una corona??
