Question

решите пожалуйста 15,16​

Answer 1

Ответ:

15

$\frac{ \sqrt{ {(x - 3)}^{2} } }{x - 3} + \frac{2 - x}{ \sqrt{ {(x - 2)}^{2} } } = \frac{x - 3}{x - 3} + \frac{2 - x}{2 - x} = 1 + 1 = 2$

16

${(16 \sqrt{2 \times 25} - 9 \sqrt{2 \times 100} + 4 \sqrt{2 \times 225} ) }^{2} \sqrt{0.04} = {(16 \times 5 \sqrt{2} - 9 \times 10 \sqrt{2} + 4 \times 15 \sqrt{2} )}^{2} \times 0.2 = {(30 \sqrt{2} - 90 \sqrt{2} + 60 \sqrt{2} )}^{2} \times 0.2 = 0 \times 0.2 = 0$
