z \cdot z^{3} + 15 = 16.66

Solution steps

z z^{3} + 15 = 16.66

Move

15

to the right side

z z^{3} = 1.66

Simplify

z^{4} = 1.66

Rewrite the equation with

u = z^{2}

and

u^{2} = z^{4}

u^{2} = 1.66

Solve

u^{2} = 1.66 : u = 1.66, u = - 1.66

u = 1.66, u = - 1.66

Substitute back

u = z^{2},

solve for

z

Solve

The solutions are

z^{3} - z^{2} + 4 z - 4 = 0

x^{4} - (4 \cdot x) + 5 = 0

y^{5} + y^{3} + y = 3

- 3 = x^{6} - 8

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