Chuyên gia,HSG giúp e nhanh nhé và check các câu khác của e nhé <3 Cho x= $\sqrt[3]{\frac{-a}{2}+ {\sqrt{a^{2}/4+1/27}}}$ + $\sqrt[3]{\frac{-a}{2} - {\sqrt{a^{2}/4+1/27}}}$ CMR x ≤ $\sqrt[3]{|a|}$

Em hứa sẽ cho 5 sao nên HSG, Chuyên gia, ai biết làm thì giúp e !!! Tìm x,y,z ∈ Z+ sao cho $\frac{x-y\sqrt{2020} }{y-z\sqrt{2020} }$ ∈ Q Tìm x,y,z để $x^{2} + y^{2} + z^{2}$ là số nguyên tố
