625 = x^{4}

x = 5, x = - 5, x = 5 i, x = - 5 i

Solution steps

625 = x^{4}

Switch sides

x^{4} = 625

Rewrite the equation with

u = x^{2}

and

u^{2} = x^{4}

u^{2} = 625

Solve

u^{2} = 625 : u = 625, u = - 625

u = 625, u = - 625

Substitute back

u = x^{2},

solve for

x

Solve

x^{2} = 625 : x = 5, x = - 5

Solve

x^{2} = - 625 : x = 5 i, x = - 5 i

The solutions are

x = 5, x = - 5, x = 5 i, x = - 5 i

x^{5} + 2 x^{3} + x^{2} + 2 = 0

- x^{3} - 5 x^{2} + 25 x + 125 = 0

2 x^{3} - 2 x^{2} - 1 = 0

x^{4} + 149 x^{2} + 4900 = 0

\frac{1}{2 a} = n^{3}
