  1. Giải đáp:
    $\frac{-5}{8}$ + x = ($\frac{-2}{3}$)²
    $\frac{-5}{8}$ + x = $\frac{4}{9}$ 
               x  = $\frac{4}{9}$ – $\frac{-5}{8}$
               x  = $\frac{32}{72}$ – $\frac{-45}{72}$
               x   = $\frac{77}{72}$
    Vậy x = $\frac{77}{72}$
        

  2. @Thỏ
    $\frac{-5}{8}$ + x = $(\frac{-2}{3})^{2}$
    ⇒ $\frac{-5}{8}$ + x = $\frac{4}{9}$
    ⇒ x = $\frac{4}{9}$ – $\frac{-5}{8}$
    ⇒ x = $\frac{77}{72}$
