Объяснение:

[tex]1) \frac{2(x + y) + z}{xyz} [/tex]

при x=0.6 y=2.1 z=8.3

[tex] \frac{2(x + y) + z}{xyz} = \frac{2(0.6 + 2.1) + 8.03}{0.6 \times 2.1 \times 8.03} = \frac{1.2 + 4.2 + 8.03}{0.6 \times 2.1 \times 8.03} = \frac{13.43}{10.1178} = 1.327[/tex]

[tex]2) \frac{0.25(p - k)}{ \frac{1}{2} p + k}[/tex]

при p=0.08 k=-0.07

[tex] \frac{0.25(p - k)}{ \frac{1}{2}p + k } = \frac{0.25(0.08 - ( - 0.07))}{0.04 + ( - 0.07)} = \frac{0.25(0.08 + 0.07)}{0.04 - 0.07} = \frac{0.25 \times 0.15}{0.04 - 0.07} = \frac{0.0375}{ - 0.03} = 1.25[/tex]
