\(\frac{0,8^5}{0,4^6}\)
\(=\frac{0,8.0,8.0,8.0,8.0,8}{0,4.0,4.0,4.0,4.0,4.0,4}\)
\(=\frac{32}{1.0,4}\)
\(=80\)
chúc bạn học tốt!!!
\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}\)
\(=\frac{\left(0,4.2\right)^5}{\left(0,4\right)^6}\)
\(=\frac{\left(0,4\right)^5.2^5}{\left(0,4\right)^6}\)
\(=\frac{2^5}{0,4}\)
\(=\frac{2^5}{0,1.2^2}\)
\(=\frac{2^3}{0,1}\)
\(=80\)
\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}\)
\(=\frac{\left(2.0,4\right)^5}{\left(0,4.0,4\right)^5}\)
\(=\frac{2^5.0,4^5}{0,4.0,4^5}\)
=\(\frac{2^5}{0,4}\)
\(=80\)
Vậy biểu thức trên có giá trị là 80.
\(\frac{0.8^5}{0.4^6}=\frac{1024}{\frac{3125}{\frac{64}{15625}}}\)\(=\frac{1024}{3125}.\frac{15625}{64}=\frac{16}{1}.\frac{5}{1}=80\)
\(\frac{\left(0,8\right)^5}{\left(0,4\right)^6}=\frac{0,8.0,8.0,8.0,8.0,8}{0,4.0,4.0,4.0,4.0,4.0,4}\\ =\frac{2.2.2.2.2.2}{1.1.1.1.1.0,4}=\frac{2^5}{0,4}\\ =80\)
\(\frac{0,8^5}{0,4^6}\)
= \(\frac{0,8.0,8.0,8.0,8.0,8}{0,4.0,4.0,4.0,4.0,4.0,4}\)
=\(\frac{32}{1.0.4}\)
