Answer 1

Ответ:

$\frac{ - 4.5 - 5( - 4.5) + 25} {2( - 4.5) {}^{3 } + 250} = \frac{ - 4.5 + 22.5 + 25}{2 \times ( - 4.5 {}^{3}) + 250 } = \frac{43}{ - 2 \times ( \frac{9}{2}) {}^{3} + 250 } = \frac{43}{ - 2 \times \frac{9 {}^{3} }{2 {}^{3} } + 250} = \frac{43}{ - \frac{9 {}^{3} }{2 {}^{2} } + 250 } = \frac{43}{ - \frac{9 {}^{3} }{4} + 250} = \frac{43}{ - \frac{9 {}^{3} + 1000}{4} } = \frac{172}{ - 9 {}^{3} + 1000} = \frac{172}{ - 729 + 1000} = \frac{172}{271}$
