16 k^{4} = 1296

k = 3, k = - 3, k = 3 i, k = - 3 i

Solution steps

16 k^{4} = 1296

Divide both sides by

16

k^{4} = 81

Rewrite the equation with

u = k^{2}

and

u^{2} = k^{4}

u^{2} = 81

Solve

u^{2} = 81 : u = 81, u = - 81

u = 81, u = - 81

Substitute back

u = k^{2},

solve for

k

Solve

k^{2} = 81 : k = 3, k = - 3

Solve

k^{2} = - 81 : k = 3 i, k = - 3 i

The solutions are

k = 3, k = - 3, k = 3 i, k = - 3 i

288 = 24 x^{12}

- x^{3} + 15 x^{2} - 75 x + 125 = 0

x, y^{2} = 2 x^{3}

8 1^{2} = b^{3}

- x^{3} + 30 x^{2} - 279 x + 810 = 0
