nha bạn

\(M=\frac{17}{5}\cdot\frac{-31}{125}\cdot\frac{1}{2}\cdot\frac{10}{17}\cdot\frac{-1}{2^3}\)

\(M=\frac{17}{5}\cdot\frac{-31}{125}\cdot\frac{1}{2}\cdot\frac{10}{7}\cdot\frac{-1}{8}\)

\(M=\left(\frac{17}{5}\cdot\frac{10}{17}\cdot\frac{1}{2}\right)\cdot\frac{-31}{125}\cdot\frac{-1}{8}\)

\(M=1\cdot\frac{31}{1000}=\frac{31}{1000}\)

\(P=\frac{6}{7}\cdot\frac{8}{13}+\frac{6}{9}\cdot\frac{9}{7}-\frac{3}{13}\cdot\frac{6}{7}=\frac{6}{7}\cdot\frac{8}{13}+\frac{6}{7}\cdot1-\frac{3}{13}\cdot\frac{6}{7}\)

\(=\frac{6}{7}\left(\frac{8}{13}+1-\frac{3}{13}\right)=\frac{6}{7}\left(\frac{8}{3}+\frac{13}{13}-\frac{3}{13}\right)=\frac{6}{7}\cdot\frac{18}{13}=\frac{108}{91}\)

\(\dfrac{17}{5}\cdot\dfrac{31}{125}\cdot\dfrac{1}{2}\cdot\dfrac{10}{17}:\dfrac{1}{8}\)

\(=\dfrac{17}{5}\cdot\dfrac{10}{17}\cdot4\cdot\dfrac{31}{125}=8\cdot\dfrac{31}{125}=\dfrac{248}{125}\)

M=17/5 x (-31)/125 x 1/2 x 10/17 x 1/2³

M=(17/5 x 1/2)x(-31/125 x 1/2³)x 10/7

M=17/10 x (-31/125 x  1/8)x 10/7

M=(17/10 x 10/17)x(-31/1000)

M=170/170 x (-31/1000)

M=1 x (-31/1000)

M= -31/1000

i don'n know
