=\(\frac{0.4^5x0.4}{2^5x0.4^5}=\frac{0.4}{2^5}=\frac{0.2}{2^4}=\frac{2}{16.10}=\frac{1}{80}\)

Câu trả lời là = 80 nhé.

\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}=80\)

=4^5          2^6

----------- * -----------

5            5

Ta có: \(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}\)

\(=\frac{2^5\cdot\left(0,4\right)^5}{\left(0,4\right)\cdot\left(0,4\right)^5}=\frac{2^5}{0,4}=\frac{32}{0,4}=80\)

\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}=\frac{\left(2.0,4\right)^5}{\left(0,4\right)^6}=\frac{2^5.\left(0,4\right)^5}{\left(0,4\right)^6}=\frac{2^5}{0,4}=\frac{32}{0,4}=80\)

\(\frac{\left(0,8^5\right)}{\left(0,4^6\right)}=80\)

nha bạn 

\(\frac{\left(0,8^5\right)}{\left(0,4^6\right)}=80\)nha  Linh Nguyễn                               ^_^

\(\frac{0,8^5}{0,4^6}=\frac{\frac{1024}{3125}}{\frac{64}{16525}}=80\)

\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}=\frac{\left(0,4.2\right)^5}{\left(0,4\right)^6}=\frac{\left(0,4\right)^5.2^5}{\left(0,4\right)^6}=\frac{2^5}{0,4}=\frac{32}{0,4}=80\)
