\(x=\frac{2^3\cdot25^2}{10^2\cdot5^3}=\frac{2^3\cdot\left(5^2\right)^2}{\left(2\cdot5\right)^2\cdot5^3}\)
\(=\frac{2^3\cdot5^4}{2^2\cdot5^2\cdot5^3}=\frac{2^3\cdot5^4}{2^2\cdot5^5}=\frac{2}{5}\)
Vậy x = 2/5
x=2^3.25^2/10^2.5^3
x=8.625/100.125
x=5000/12500
x=10/25
x=0,4
\(x=\frac{2^3.25^2}{10^2.5^3}=\frac{2^3.5^4}{2^2.5^2.5^3}=\frac{2^3.5^4}{2^2.5^5}\)\(=\frac{2}{5}\)
\(x=\frac{2^3.25^2}{10^2.5^3}\)
\(=\frac{2^3.\left(5^2\right)^2}{\left(2.5\right)^2.5^3}\)
\(=\frac{2^3.5^4}{2^2.5^2.5^3}\)
\(=\frac{8.\left(5^2\right)^2}{4.25.\left(5^2.5^1\right)}\)
\(=\frac{4.2.\left[\left(5^2\right).\left(5^2\right)\right]}{4.25.25.5}=\frac{4.2.25.25}{4.25.25.5}=\frac{2}{5}\)
