3√5+³√4-√5+3³√4-2√5=

tylko wszystkie obliczenia po kolei

8:√2= $8:\sqrt{2}= \frac{4*2}{\sqrt{2}}=4* \frac{2}{\sqrt{2}}=4*{\sqrt{2}=4{\sqrt{2}$

50:√2= $50:\sqrt{2}=\frac{25*2}{\sqrt{2}}=25*\frac{2}{\sqrt{2}}=25{\sqrt{2}$

3√5+³√4-√5+3³√4-2√5= $3\sqrt{5}+\sqrt[3]{4}-\sqrt{5}+3\sqrt[3]{4}-2\sqrt{5}=3\sqrt{5}-\sqrt{5}-2\sqrt{5}+\sqrt[3]{4}+3\sqrt[3]{4}=4\sqrt[3]{4}$
