Question

x\(^5\): x\(^2\) = \(\dfrac{1}{64}\)

Answer 1

\(x^5:x^2=\dfrac{1}{64}\\ \dfrac{x^5}{x^2}=\dfrac{1}{64}\\ x^3=\left(\dfrac{1}{4}\right)^3\\ \Rightarrow x=\dfrac{1}{4}\)

Vậy \(x=\dfrac{1}{4}\)

Answer 2

\(x^5:x^2=\dfrac{1}{64}\)

\(\Rightarrow x^3=\dfrac{1}{64}\)

\(\Rightarrow x^3=\left(\dfrac{1}{4}\right)^3\)

\(\Rightarrow x=\dfrac{1}{4}\)
