Answer 1

Ответ:

$\frac{ {x}^{2} - 25}{ {x}^{2} } \div \frac{ {x}^{2} - 10x + 25}{ {x}^{3} - 5 {x}^{2} } = \frac{(x - 5)(x + 5)}{ {x}^{2} } \div \frac{(x - 5) {}^{2} }{x( {x}^{2} - 5x)} = \frac{(x - 5)(x + 5)}{ {x}^{2} } \times \frac{x( {x}^{2} - 5)}{ {(x - 5)}^{2} } = \frac{(x + 5)( {x}^{2} - 5) }{x(x - 5)} = \frac{(x + 5) {}^{2} }{x}$
