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

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: \(\frac{2^3.3^4}{2^2.3^2.5}\)

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

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

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

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

\(2^3.\frac{3}{2^2}.3^2.5=8.\frac{3}{4}.9.5=6.9.5=54.5=270\)

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

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

ta có

a=2^3.3

b=2.3^2.5^2

c=2^2.3^4.5^2a

=>(a,b,c)=2.3=6

vay UCLN(a,b,c)=6

đó là 6

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

Giúp mình với

\(\frac{2^3.3^4}{2^2.3^2.5}=\frac{2.3^2}{1.1.5}=\frac{2.9}{5}=\frac{18}{5}\)

muốn rút gọn phân số đó ta làm như sau:

\(\frac{2^3\cdot3}{2^2\cdot3^2\cdot5}\)=\(\frac{2}{3\cdot5}\)=\(\frac{2}{15}\)

=2.3^2/5

=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

\(\frac{2^3\cdot3^4}{2^2\cdot3^2\cdot5}=\frac{2\cdot3^3}{5}=\frac{2\cdot9}{5}=\frac{18}{5}\)

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

18 phần 5

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