Answer 6

Đặt \(a=\sqrt[3]{16x-24};b=\sqrt[3]{1-3x};c=\sqrt[3]{19x-25}\)

Ta có: \(b^3+c^3=1-3x+19x-25=a^3\)

Ta lại có: \(a=b+c\)
=>\(a^3=\left(b+c\right)^3\)

=>\(a^3=b^3+c^3+3bc\left(b+c\right)\)

\(0=\text{3bc(b+c)}\)
\(0=bc\left(b+c\right)\)
=>\(\orbr{\frac{\begin{cases}c=0\\b=0\end{cases}}{b+c=0}}\)
