Sap xep cac ket qua trong cac gia tri duoi day tu be den lon
a, \(x-\frac{2}{7}=\frac{8}{21}\)
b,\(\frac{7}{4}-\)\(\left[\frac{2}{3}-\left(\frac{1}{2}-\frac{3}{8}\right)\right]\)
c, \(\frac{11}{13}-\left(\frac{5}{42}+x\right)=-\frac{15}{28}+\frac{11}{13}\)
d, \(x^4=16\)
e,\(\frac{3}{4}-\)\(\left[-\left(-\frac{5}{3}\right)-\left(\frac{1}{12}+\frac{2}{9}\right)\right]\)
g,gia tri bieu thuc \(\left(\frac{1}{5}+\frac{1}{8}+\frac{3}{8}\right)+x\) tai \(x=\frac{-1}{2}\)
h,\(\frac{1}{11}+\frac{2}{3}+\frac{-19}{33}\)
i, gia tri x thoa man \(\frac{-\left(-x\right)}{5}-\frac{2}{10}=\frac{1}{-5}-\frac{7}{50}\)
k,\(\frac{-6}{11}+\frac{12}{-7}+\frac{-33}{77}\)
l,\(\left(\frac{1}{6}+\frac{1}{10}-\frac{1}{15}\right)+x=0\)
m,\(-\frac{2}{5}\le x-\frac{7}{5}<\frac{3}{5}\)
n,\(x+\left(-\frac{3}{10}+\frac{5}{12}-\frac{4}{5}\right)tai\) \(x=-\frac{1}{3}\)
