x^{4} = 625

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

Solution steps

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

20 = [5 + \frac{0.12 x}{10}]^{20}

x^{4} - 4 x^{2} = 0

x^{4} - 3 x^{2} + 1 = 0

x^{3} = 729

x^{4} - 11 x^{2} + 10 = 0
