solve for

x, x^{4} = 16

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

Solution steps

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

2 = 3 x^{5} + x - 2

4 x^{3} - 48 x = 0

10 x^{3} - 1000 x = 0

(y^{2} - 1)^{2} + 3 (y^{2} - 1) - 18 = 0

m^{4} - 10 m^{2} + 25 = 0
