Tìm x a) |2x - 3|= |x+5| b)|4 - 2x| = |3 + x| c) | 4x - 5| - |2x +1| = 0 d) |0,5x - 2| - |x + 2/3| = 0

giải pt: $\sqrt[3]{x-1}$+ $\sqrt[3]{x-21}$ =$\sqrt[3]{2x-3}$

giả pt: $\sqrt[3]{1-x}$+ $\sqrt[3]{1+x}$=1

giải pt: 2$\sqrt[3]{2x-1}$= $x^{3}$+1

giải pt : $\sqrt[2]{2x^2-1}$+ $\sqrt[2]{x^2-3x-2}$= $\sqrt[2]{2x^2+2x+3}$+ $\sqrt[2]{x^2-x+2}$

Mn giải giúp mình nha cảm ơn mn nhiều Mình đang cần gấp Bài 14,15 vẽ hình nha
