rút gọn M =\(\frac{3}{229}\left(2+\frac{1}{433}\right)-\frac{1}{229}-\frac{432}{433}-\frac{4}{229.433}\)
Cho biểu thức :
M=\(\frac{3}{229}.\left(2+\frac{1}{433}\right)-\frac{1}{229}\cdot\frac{432}{433}-\frac{4}{229.433}\)
Tính giá trị của M.
M=\(\frac{3}{229}.\left(2+\frac{1}{433}\right)\) -\(\frac{1}{229}\) .\(\frac{432}{433}\) -\(\frac{4}{229.433}\)
jup mih với!cảm ơn
3/229 x ( 2 + 1/433 ) - 1/229 x 432/433 - 4/229x433
= ( 3/229 x 867/433 ) - ( 432/99157 - 4/99157 )
= 2601/99157 - 432/99157 - 4/99157
= 5/229

\(M=\frac{3}{299}\cdot\left(2+\frac{1}{433}\right)-\frac{1}{299}\cdot\frac{432}{433}-\frac{4}{229.433}\)
\(M=\left(\frac{3}{229}\cdot\frac{867}{433}\right)-\left(\frac{432}{99157}-\frac{4}{99157}\right)\)
\(M=\frac{2601}{99157}-\frac{432}{99157}-\frac{4}{99157}\)
\(M=\frac{5}{229}\)
Tính
M=\(\frac{3}{229}\).2\(\frac{1}{433}\)-\(\frac{1}{229}\).\(\frac{432}{433}\)-\(\frac{4}{229.433}\)
Cho biểu thức A =\(\frac{3}{229}.2\frac{1}{433}-\frac{1}{229}.\frac{432}{433}-\frac{4}{229.433}\)
a) Bằng cách đặt a = \(\frac{1}{229}\), b = \(\frac{1}{433}\). Rút gọn biểu thức A theo a và b
b) tính giá trị biểu thức A
a, \(A=3a.2.b-a.432b-4ab\)
\(=6ab-432ab-4ab=-430ab\)
b, \(A=-430ab=\left(-430\right).\frac{1}{229}.\frac{1}{433}=\frac{-430}{229.433}\)

Tính giá trị biểu thức:
a) \(M=\frac{3}{299}.\left(2+\frac{1}{433}\right)-\frac{1}{229}.\frac{432}{433}-\frac{4}{229.433}\)
b) \(N=3.\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.119}+\frac{8}{39}\)
\(M=2\frac{1}{433}\frac{3}{229}-\frac{432}{433}.\frac{1}{229}-\frac{4}{433.229}\)
\(N=3\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.119}-\frac{8}{39}\)
Tính :
a)\(M=2\frac{1}{433}\cdot\frac{3}{229}-\frac{432}{433}\cdot\frac{1}{229}-\frac{4}{433\cdot119}\)
b)\(N=3\frac{1}{117}\cdot\frac{1}{119}-\frac{4}{117}\cdot5\frac{118}{119}-\frac{5}{117\cdot119}-\frac{8}{39}\)
