=2.9/5
=18/8
Bài làm
2³.3⁴/2² . 3² . 5
= 2 . 3²/5
= 2 . 9 / 5
= 18 / 5
Vậy giá trị của biểu thức trên là 18/5
\(\frac{2^3\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2\cdot3^3}{5}=\frac{2\cdot9}{5}=\frac{18}{5}\)
\(\frac{2^3.3^4}{2^2.3^2.5}=\frac{2^2.2.3^2.3^2}{2^2.3^2.5}=\frac{2.3^2}{5}=\frac{2.9}{5}=\frac{18}{5}\)
\(\frac{2^3.3^4}{2^2.3^2.5}=\frac{2^2.3^2}{5}=\frac{36}{5}\)
\(=\frac{2^2.2^1.3^2.3^2}{2^2.3^2.5}\)\(=\frac{2.3^2}{5}\)\(=\frac{2.9}{5}\)\(=\frac{18}{5}\)

\(\frac{2^3.3^4}{2^2.3^2.5}\)
\(=\frac{2.3^2}{5}\)
\(=\frac{2.9}{5}\)
\(=\frac{18}{5}\)
Trả lời:
\(\frac{2^3.3^4}{2^2.3^2.5}=\frac{2.3^2}{5}=\frac{2.9}{5}=\frac{18}{5}\)
