Question

Determinati multimea solutilor ecuatiei:
$5x {}^{2} = (20 - \sqrt[5]{3} ) \sqrt{19 - \sqrt[8]{3} }$
Va rog am mare nevoie ,dau coroana​

Answer 1

Răspuns:

x²=$\frac{1}{5} (20-\sqrt[3]{5} )*\sqrt{19-\sqrt[8]{3} }$

x=±$\sqrt{\frac{1}{5}*(20-\sqrt[5]{3} *\sqrt{19-\sqrt[8]{3} } }$

x1=+$\sqrt{1/5*(20-\sqrt[5]{3}) \sqrt{19-\sqrt[8]{3} } }$

x2=-$\sqrt{1/5*(20-\sqrt[5]{3} )*\sqrt{19-\sqrt[8]{3} } }$

S={x1,x2}
