$1)(0.24 {)}^{5} \times ( \frac{25}{6} {)}^{ - 5} \times ( \frac{6}{25} {)}^{4} =$
$2)3.5 \times 1 {0}^{10} \times (0.25 \times 1 {0}^{7} {)}^{ - 1} =$
$3) \frac{ {4}^{7} \times {6}^{4} \times {2}^{3} }{1 {6}^{5} \times {2}^{5} \times {5}^{ - 2} } =$
$4) \frac{( {y}^{4} \times {y}^{5}) }{ {y}^{15} }.y = \frac{4}{5}$

Answer 1

а)=
$( \frac{6}{25} ) {}^{5} \times ( \frac{6}{25} ) {}^{5} \times ( \frac{6}{25}) {}^{4} = ( \frac{6}{25} ) {}^{14}$
