LỜI GIẢI

\(\frac{2^7.9^3}{6^5.8^2}=\frac{93312}{497664}=\frac{3}{16}\)

Tk cho mk nhé bạn

Rút gọn luôn bằng 3/16

\(\frac{2^7.9^3}{6^5.8^2}\)

\(=\frac{2^7.3^6}{2^5.3^5.2^6}\)

\(=\frac{2^7.3^6}{2^{11}.3^5}\)

\(=\frac{3}{2^4}\)

\(=\frac{3}{16}\)

\(\frac{2^7.9^3}{6^5.8^2}=\frac{2^6+2.3^5+3}{3^5.2^5.2^6}=\frac{6}{2^6}=\frac{3}{32}\)

\(\frac{93312}{497664}\)

\(\frac{6^2}{5\cdot7}\cdot\frac{7^2}{6\cdot8}\cdot\frac{8^2}{7\cdot9}\cdot\frac{9^2}{8\cdot10}\)

=\(\frac{6\cdot6}{5\cdot7}\cdot\frac{7\cdot7}{6\cdot8}\cdot\frac{8\cdot8}{7\cdot9}\cdot\frac{9\cdot9}{8\cdot10}\)

=\(\frac{6\cdot7\cdot8\cdot9}{5\cdot6\cdot7\cdot8}\cdot\frac{6\cdot7\cdot8\cdot9}{7\cdot8\cdot9\cdot10}\)

=\(\frac{9}{5}\cdot\frac{3}{5}\)=\(\frac{27}{25}\)

**** MIK

\(=\frac{6.6}{5.7}.\frac{7.7}{6.8}.\frac{8.8}{7.9}.\frac{9.9}{8.10}\)

\(=\frac{6.6.7.7.8.8.9.9}{5.6.7.8.9.10.8.7}\)

\(=\frac{27}{25}\)
