Question

\(\left(\frac{2}{5}\right)^2.x=\left(\frac{2}{5}\right)^5\)

Answer 1

\(\left(\frac{2}{5}\right)^2\cdot x=\left(\frac{2}{5}\right)^5\)

\(x=\left(\frac{2}{5}\right)^5:\left(\frac{2}{5}\right)^2\)

\(x=\left(\frac{2}{5}\right)^3\)

\(x=\frac{8}{125}\)

Answer 2

\(\left(\frac{2}{5}\right)^2.x=\left(\frac{2}{5}\right)^5\)

\(\Rightarrow x=\left(\frac{2}{5}\right)^5:\left(\frac{2}{5}\right)^2\)

\(\Rightarrow x=\left(\frac{2}{5}\right)^3\)

\(\Rightarrow x=\frac{8}{125}.\)

Vậy \(x=\frac{8}{125}.\)

Chúc bạn học tốt!

Answer 3

\(\left(\frac{2}{5}\right)^2.x=\left(\frac{2}{5}\right)^5\\ x=\left(\frac{2}{3}\right)^5:\left(\frac{2}{5}\right)^2\\ x=\left(\frac{2}{5}\right)^3\\ x=\frac{8}{25}\)

Answer 4

\(\left(\frac{2}{5}\right)^2.x=\left(\frac{2}{5}\right)^5\)

x=\(\left(\frac{2}{5}\right)^5\div\left(\frac{2}{5}\right)^2\)

x=\(\left(\frac{2}{5}\right)^{5-2}\)

x=\(\left(\frac{2}{5}\right)^3\)
