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

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

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: \(\frac{2^3.3^4}{2^2.3^2.5}\)

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

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

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

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

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

TA CÓ : \(\frac{2^3.3^4}{2^2.3^2.5}\)= \(\frac{2^3.3^4}{\left(2.3\right)^2.5}\)= \(\frac{2^3.3^4}{6^2.5}\)= \(\frac{2^3.3^4}{36.5}\)= \(\frac{8.81}{180}\)=  \(\frac{648}{180}\)= 648 : 180 = 3,6 HOẶC \(\frac{648}{180}\)= \(\frac{18}{5}\)

câu b) thì sao bạn

ngu..............................

tao lao

a)\(\frac{121212}{131313}=\frac{121212:10101}{131313:10101}=\frac{12}{13}\)

b)\(\frac{2^3\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2^2\cdot3^2\cdot3^2.2}{2^2\cdot3^2\cdot5}=\frac{3^2\cdot2}{5}=\frac{9\cdot2}{5}=\frac{18}{5}\)

a) 121212/131313 = 121212 : 1010/131313 : 1010 = 12/13.

a)\(\frac{121212}{131313}=\frac{121212:10101}{131313:10101}=\frac{12}{13}\)

b)\(\frac{2^3\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2^2\cdot3^2\cdot3^2.2}{2^2\cdot3^2\cdot5}=\frac{3^2\cdot2}{5}=\frac{9\cdot2}{5}=\frac{18}{5}\)

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

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

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

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

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
