ta có: \(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}=\frac{\left(0,4\times2\right)^5}{\left(0,4\right)^6}=\frac{\left(0,4\right)^5\times2^{^5}}{\left(0,4\right)^6}=\frac{1\times32}{0,4}=80\)
\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}=\frac{0,32768}{0,004096}=80\)
nhấn đúng cho mk nha các ban !!!!!!!!!!!!!!!!!!!!!!!!!
