Ta có:

\(\frac{2^2.2.3^2.3^2}{2^2.3^2.5}\) =\(\frac{2.3^2}{5}\) =\(\frac{18}{5}\)

Vậy

Ta cã: \(\frac{2^3.3^4}{2^2.3^2.5}\)

\(=\frac{2^2.2.3^2.3^2}{2^2.3^2.5}\)

\(=\frac{2.3^2}{5}\)

\(=\frac{18}{5}\)

\(=\frac{2.3^2}{5}=\frac{18}{5}\)

\(\frac{2^3.3^4}{2^2.3^2.5}=\frac{2^2.3^2.2.3^2}{2^2.3^2.5}=\frac{2^2.3^2.18}{2^2.3^2.5}=\frac{18}{5}\)

\(\frac{2^3.3}{2^23^2.5}=\frac{2}{3.5}=\frac{2}{15}\)

\(\frac{2^3.3}{2^2.3^2.5}=\frac{2}{3.5}=\frac{2}{15}\)

Thiếu dấu nhân ở chỗ \(2^2.3^2\)nha 

cho mik hỏi bạn tùng lâm là bạn hướng dẫn mik cách giải bài này đc ko tại vì mik vẫn còn mấy bài giống vậy

\(\frac{2^3\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2^2\cdot2\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2\cdot3^4}{3^2\cdot5}=\frac{2\cdot3^2}{5}=\frac{18}{5}\)

18 phần 5

\(\frac{2^3.3^4}{2^2.3^2.5}\)= \(\frac{2.3^2}{1.1.5}\)= \(\frac{18}{5}\)

=^_^=

k mình nha

\(\dfrac{2^3.3^4}{2^3.3^2.5}=\dfrac{1.3^2}{1.1.5}=\dfrac{9}{5}\)

Ta có :2^3.3^4/2^2.3^2.5=2.3^2/1.1.5=2.9/5=\(\dfrac{18}{5}\)

\(\frac{2^3.3}{2^2.3^2.5}=\frac{2^2.2^1.3}{2^2.3.3.5}=\frac{2}{3.5}=\frac{2}{15}\)

\(\frac{2^3.3}{2^2.3^2.5}=\frac{24}{180}=\frac{2}{15}\)

\(\frac{\sqrt{2^3\cdot3^4\cdot5^5\cdot6^6\cdot7^7}}{2^2\cdot3^2\cdot5^6\cdot6^3\cdot7^3}=\frac{2\cdot3^2\cdot5^2\cdot6^3\cdot7^3\cdot\sqrt{2\cdot5\cdot7}}{2^2\cdot3^2\cdot5^6\cdot6^3\cdot7^3}=\frac{\sqrt{2\cdot5\cdot7}}{2\cdot5^4}=\frac{\sqrt{70}}{1250}\)
