\(\frac{143.56.34}{32.187.52}\)=\(\frac{272272}{311168}\)=\(\frac{19448}{17017}\)
Ko chắc nhé !
Hok tốt !
\(\frac{143.56.34}{32.187.52}=\frac{13.14.17}{16.17.13}=\frac{14}{16}=\frac{7}{8}\)
\(\frac{143.56.34}{32.187.52}\)
\(=\frac{11.13.2^3.7\cdot2.17}{2^5.11.17.2^2.13}\)
\(=\frac{2^{3+1}.7}{2^{5+2}}\)
\(=\frac{2^4.7}{2^7}\)
\(=\frac{7}{2^3}\)
\(=\frac{7}{8}\)
~Study well~

\(\frac{143.8.7.17.2}{4.8.187.27.2}\)=\(\frac{19448}{17017}\)= Vậy được chưa
Mk ko viết lại đề nhá !
Hình như là chưa
Đấy vx chưa pk cách tính nhanh
\(\frac{143.56.34}{32.187.52}=\frac{13.11.8.7.2.17}{8.4.11.17.4.13}\)
\(=\frac{7.2}{4.4}=\frac{7.1}{4.2}=\frac{7}{8}\)
\(\frac{143\cdot56\cdot34}{32\cdot187\cdot52}\)
\(=\frac{13\cdot14\cdot17}{16\cdot17\cdot13}\)
\(=\frac{14}{16}=\frac{7}{8}\)
#Ad oii...
\(\frac{143\times56\times34}{32\times187\times52}\)
\(=\frac{11\times13\times2^3\times7\times2\times17}{2^5\times11\times17\times2^2\times13}\)
\(=\frac{14}{16}=\frac{7}{8}\)

Làm cách bth
Cách 1:
\(\frac{143.56.34}{32.187.52}=\frac{272272}{311168}=\frac{7}{8}\)
Chúc bạn học tốt !!!
Cách 2:
\(\frac{143.56.34}{32.187.52}=\frac{11.13.2^3.7.2.17}{2^5.11.17.2^2.13}=\frac{11.13.2^4.7.17}{2^7.11.17.13}=\frac{7}{2^3}=\frac{7}{8}\)
Chúc bạn học tốt !!!
