Question

Номер 1.9 пример 3, 4.

Answer 1

3) х1=2

у1=8

4) $x_{1} = frac{1}{left(sqrt{3} + 2right)^{frac{2}{3}}} left(sqrt[3]{sqrt{3} + 2} + sqrt{3} + 2right) </p><p> = frac{1}{left(sqrt{3} + 2right)^{frac{2}{3}}} left(sqrt[3]{sqrt{3} + 2} + sqrt{3} + 2right) = 2.195$

$y_{1} = frac{9}{sqrt[3]{27 sqrt{3} + 54}} + 4 + sqrt[3]{27 sqrt{3} + 54} = frac{3}{sqrt[3]{sqrt{3} + 2}} + 4 + 3 sqrt[3]{sqrt{3} + 2} = 10.587$
