Question

(1/125 - x³) (x² + 2².2⁶)=0

Answer 1

( \(\dfrac{1}{125}\) - \(x^3\) ) ( \(x^2\) + 2².6⁶) = 0

\(\left[{}\begin{matrix}\dfrac{1}{125}-x^3=0\\x^2-2^2.6^6=0\end{matrix}\right.\)

\(\left[{}\begin{matrix}x^3=\dfrac{1}{125}\\x^2=2^2(6^3)^2\end{matrix}\right.\)

\(\left[{}\begin{matrix}x=\dfrac{1}{5}\\x^2=(2.6^3)^2\end{matrix}\right.\)

\(\left[{}\begin{matrix}x=\dfrac{1}{5}\\x=432^2\end{matrix}\right.\)

\(\left[{}\begin{matrix}x=\dfrac{1}{5}\\x=432\\x=-432\end{matrix}\right.\)

\(x\) ϵ { -432; \(\dfrac{1}{5}\); 432; }
