Solve 76=8k^4 - ScanMath

Evaluate

76 = 8 k^{4}

Swap the sides of the equation

8 k^{4} = 76

Divide both sides

\frac{8 k ^{4}}{8} = \frac{76}{8}

Divide the numbers

k^{4} = \frac{76}{8}

Cancel out the common factor 4

k^{4} = \frac{19}{2}

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

k = \pm 4 \frac{19}{2}

Simplify the expression

More Steps

k = \pm \frac{4 152}{2}

Separate the equation into 2 possible cases

k = \frac{4 152}{2} k = - \frac{4 152}{2}

Solution

k_{1} = - \frac{4 152}{2}, k_{2} = \frac{4 152}{2}

Alternative Form

k_{1} \approx - 1.755622, k_{2} \approx 1.755622
