Bấm máy tính ý ngu ạ

1/9-5/6-4/7/12-1/36-10

=6/54-45/54-216/54/21/36-1/36-360/36

=-255/54/-340/36

=-85/18-85/9

=-85/18-170/18

=-255/18

=-85/6

a) \(\frac{7}{11}\)

b)\(\frac{218}{165}\)

c)\(\frac{1}{4}\)

d)\(\frac{-21}{20}\)

e)\(\frac{2}{9}\)

g) 1

h)\(\frac{-561}{26}\)

i)\(\frac{4}{3}\)

a) \(x-\frac{5}{7}=\frac{1}{9}\Rightarrow x=\frac{1}{9}+\frac{5}{7}\Rightarrow x=\frac{52}{63}\)

b) \(\frac{-3}{7}-x=\frac{4}{5}+\frac{-2}{3}\Rightarrow\frac{-3}{7}-x=\frac{2}{15}\Rightarrow x=\frac{-3}{7}-\frac{2}{15}\Rightarrow x=\frac{-59}{105}\)

c) \(x-\frac{1}{5}=\frac{2}{7}.\frac{-11}{5}\Rightarrow x-\frac{1}{5}=\frac{-22}{35}\Rightarrow x=\frac{-22}{35}+\frac{1}{5}\Rightarrow x=\frac{-3}{7}\)

d) \(\frac{x}{182}=\frac{-6}{14}.\frac{35}{91}\Rightarrow\frac{x}{182}=\frac{-15}{91}\Rightarrow x=\frac{\left(-15\right).182}{91}\Rightarrow x=-30\)

bằng 3083/56

\(56-\frac{53}{56}\)\(=\frac{3136}{56}-\frac{53}{56}=\frac{3038}{56}=\frac{3038:14}{56:14}=\frac{217}{4}\)

giup mk voi

\(\frac{\left(-2\right)^3.3^3.5^3.7.8}{3.5^3.2^4.42}\)

\(=\frac{-8.27.125.7.8}{3.125.16.42}\)

\(=\frac{-8.3.9.125.7.8}{3.125.8.2.7.6}\)

\(=\frac{-72}{12}\)

\(=-6\)

1 độ C bằng 274,15 độ K nên nếu bạn muốn dổi từ độ C sang K thì lấy số độ C nhân cho 274,15 là ra độ K
