Solve -(2x^3)=5 - ScanMath

Evaluate

- 2 x^{3} = 5

Change the signs on both sides of the equation

2 x^{3} = - 5

Divide both sides

\frac{2 x ^{3}}{2} = \frac{- 5}{2}

Divide the numbers

x^{3} = \frac{- 5}{2}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

x^{3} = - \frac{5}{2}

Take the 3 -th root on both sides of the equation

3 x^{3} = 3 - \frac{5}{2}

Calculate

x = 3 - \frac{5}{2}
