Tìm x

\(x:\left(\dfrac{-1}{2}\right)^3=\dfrac{-1}{2}\)

Answer 1

\(x:\left(\dfrac{-1}{2}\right)^3=\dfrac{-1}{2}\)

\(\Rightarrow x=\dfrac{-1}{2}.\left(\dfrac{-1}{2}\right)^3=\left(\dfrac{-1}{2}\right)^4\)

\(\Rightarrow x=\dfrac{1}{16}\)

Answer 2

x : (-\(\dfrac{1}{2}\))³ = -\(\dfrac{1}{2}\)

<=> -\(\dfrac{1}{2}.\left(-\dfrac{1}{2}\right)^3=x\)

<=> x = (-\(\dfrac{1}{2}\))⁴ = x

<=> x = \(\dfrac{1}{16}\)

Answer 3

\(x:\left(\dfrac{-1}{2}\right)^3=\dfrac{-1}{2}\)

\(x=\dfrac{-1}{2}.\left(\dfrac{-1}{2}\right)^3\)

\(x=\dfrac{-1}{2}.\dfrac{-3}{6}\)

\(x=\dfrac{3}{12}\)

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