giúp mình với !!!

Tính:\(\frac{\frac{2}{3}+3\left(\frac{2}{3}\right)^3+\left(\frac{5}{6}\right)^2}{\frac{7}{60}:\left(\frac{35}{31.37}+\frac{35}{37.43}+\frac{105}{43.61}+\frac{35}{61.67}\right)}\)

cảm ơn các bạn rất nhiều!

A=\(\frac{35}{31.37}\)+\(\frac{35}{37.43}\)+\(\frac{105}{43.61}\) +\(\frac{35}{61.67}\)

\(\frac{\frac{2}{3}+3\left(\frac{2}{3}\right)^3-\left(\frac{5}{6}\right)^2}{\frac{7}{60}:\left(\frac{35}{31\cdot37}+\frac{35}{37\cdot43}+\frac{105}{43\cdot61}+\frac{35}{61\cdot67}\right)}\)

Tính hợp lí:

a)\(\left(\frac{-1}{2}\right)-\left(\frac{-3}{5}\right)+\left(\frac{-1}{9}\right)+\frac{1}{127}\)\(-\left(+\frac{7}{18}\right)+\frac{4}{35}-\left(\frac{-2}{7}\right)\)

b)\(\frac{3}{5}+\frac{3}{11}-\left(\frac{-3}{7}\right)+\)\(\left(\frac{2}{97}\right)-\frac{1}{35}-\frac{3}{4}+\left(\frac{-23}{44}\right)\)

1/ Tính giá trị biểu thức

A=\(\frac{7}{35}+\left(-1\frac{3}{4}+\frac{12}{7}\right)-\left(\frac{1}{4}-\frac{2}{7}-\frac{13}{35}\right)-\frac{3}{7}\)\(\frac{3}{7}\)

B=\(\sqrt{\frac{25}{16}-\frac{\left(-3\right)^2}{\left|-4\right|}}+\frac{\sqrt{\left(-7\right)^2}}{4}-3.\left(\frac{5}{2}\right)^2\)

Tính giá trị của biểu thức B= (2/3+3*(2/3)^3-(5/6)^2):(7/60/(35/31.37+35/37.43+105/43.61+35/61.67)) toán 6

Tìm x biết:

a)\(\frac{2}{3}.\left(x-\frac{3}{8}\right)-x-\left(-\frac{7}{8}+\frac{2}{3}\right)=\left(\frac{-3}{4}\right)^3:1\frac{11}{16}\)

b)\(-\frac{7}{8}+\frac{7}{8}:\left(\frac{2}{3}-x\right)+\frac{5}{6}:\left(-1\frac{11}{35}\right)=\left(0,8\right)^2\)
