Solve 5(2x^4) = 15

Evaluate

5 \times 2 x^{4} = 15

Multiply the numbers

10 x^{4} = 15

Divide both sides

\frac{10 x ^{4}}{10} = \frac{15}{10}

Divide the numbers

x^{4} = \frac{15}{10}

Cancel out the common factor 5

x^{4} = \frac{3}{2}

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

x = \pm 4 \frac{3}{2}

Simplify the expression

More Steps

x = \pm \frac{4 24}{2}

Separate the equation into 2 possible cases

x = \frac{4 24}{2} x = - \frac{4 24}{2}

Solution

x_{1} = - \frac{4 24}{2}, x_{2} = \frac{4 24}{2}

Alternative Form

x_{1} \approx - 1.106682, x_{2} \approx 1.106682
