Объяснение:

xy=8

x =  frac{1}{4}{y}^{2}

 frac{1}{4}  {y}^{2}  times y = 8

 frac{1}{4}  {y}^{3}  = 8

 {y}^{3}  = 32 \ y = 2 sqrt[3]{4}

x =  frac{1}{4}  times  {(2 sqrt[3]{4})^{2} } \ x = 2 sqrt[3]{2}

2 sqrt[3]{2}  times 2 sqrt[3]{4}  = 8 \ 4 times  2sqrt[3]{2}  - ( {2sqrt[3]{4})}^{2}= 0

8=8

0=0
