Solve 8x x^3 = 89

Evaluate

8 x \times x^{3} = 89

Multiply

More Steps

8 x^{4} = 89

Divide both sides

\frac{8 x ^{4}}{8} = \frac{89}{8}

Divide the numbers

x^{4} = \frac{89}{8}

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 4 \frac{89}{8}

Simplify the expression

More Steps

x = \pm \frac{4 178}{2}

Separate the equation into 2 possible cases

x = \frac{4 178}{2} x = - \frac{4 178}{2}

Solution

x_{1} = - \frac{4 178}{2}, x_{2} = \frac{4 178}{2}

Alternative Form

x_{1} \approx - 1.826312, x_{2} \approx 1.826312
