-2^2/ 9+4/9.[-(2012/2/7-2012/2/7): |-1/2|]
M=m=(7/2012+7/9-1/4):(5/9-3/2012-1/2)
con ngu nay may ko biet lam ak ma con hoi
ko biết thí mới hỏi chứ. Vậy mà cũng chửi. Vô duyên . Người tui nói là Kiên Nguyễn Trung
M = [(7.7 + 7.2012 - 1.4527)/2012.9] : [(5.2012 - 3.9 - 1.9054)/2012.9]
M = (7.9 + 7.2012 - 1.4527) / (5.2012 - 3.9 - 1.9054)
M = (63 + 14084 - 4527) / (10060 - 27 - 9054)
M = 9620/979
a) tinh M=7/2012+7/9-1/4 / 5/9-3/2012-1/2
M=\(\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\) tính M
1.tính M=\(\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\)
\(M=\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
\(M=\frac{\frac{63}{18108}-\frac{14084}{18108}-\frac{4527}{18108}}{\frac{10060}{18108}-\frac{27}{18108}-\frac{9054}{18108}}\)
\(M=\frac{-18548}{979}\)
Mình tin chắc đề bài sai , số to quá !!!
Tính \(M=\frac{\frac{7}{2012}+\frac{7}{9}+\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
\(\frac{\frac{7}{2012}+\frac{7}{9}+\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}=\left(\frac{7}{2012}+\frac{7}{9}+\frac{1}{4}\right):\left(\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}\right)\)
\(=\frac{9337}{9054}:\frac{97}{18108}=\frac{9337}{9054}.\frac{18108}{97}=\frac{18674}{97}\)
tính:
B=\(\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
Tính \(M=\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\)
1.tính M=\(\dfrac{\dfrac{7}{2012}+\dfrac{7}{9}-\dfrac{1}{4}}{\dfrac{5}{9}-\dfrac{3}{2012}-\dfrac{1}{2}}\)
Tính:
\(\frac{\frac{7}{2012}+\frac{7}{9}-\frac{1}{4}}{\frac{5}{9}-\frac{3}{2012}-\frac{1}{2}}\)
