16 = x^{4}

x = 2, x = - 2, x = 2 i, x = - 2 i

Solution steps

16 = x^{4}

Switch sides

x^{4} = 16

Rewrite the equation with

u = x^{2}

and

u^{2} = x^{4}

u^{2} = 16

Solve

u^{2} = 16 : u = 16, u = - 16

u = 16, u = - 16

Substitute back

u = x^{2},

solve for

x

Solve

x^{2} = 16 : x = 2, x = - 2

Solve

x^{2} = - 16 : x = 2 i, x = - 2 i

The solutions are

x = 2, x = - 2, x = 2 i, x = - 2 i

8 x^{3} + 4 x^{2} - 50 x - 25 = 0

(- 4 x^{6})^{2} = - 4^{2} x 6^{2}

x^{4} - 31 x^{2} + 150 = 0

x^{8} = - 1

x^{8} = 32
