Solve 17 = k^4 - -13

Evaluate

17 = k^{4} + 13

Swap the sides of the equation

k^{4} + 13 = 17

Move the constant to the right-hand side and change its sign

k^{4} = 17 - 13

Subtract the numbers

k^{4} = 4

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

k = \pm 44

Simplify the expression

More Steps

k = \pm 2

Separate the equation into 2 possible cases

k = 2 k = - 2

Solution

k_{1} = - 2, k_{2} = 2

Alternative Form

k_{1} \approx - 1.414214, k_{2} \approx 1.414214
