2 b^{8} - 18 b^{6} = 0

b = 0, b = 3, b = - 3

Solution steps

2 b^{8} - 18 b^{6} = 0

Rewrite the equation with

u = b^{2}, u^{3} = b^{6}

and

u^{4} = b^{8}

2 u^{4} - 18 u^{3} = 0

Solve

2 u^{4} - 18 u^{3} = 0 : u = 0, u = 9

u = 0, u = 9

Substitute back

u = b^{2},

solve for

b

Solve

b^{2} = 0 : b = 0

Solve

b^{2} = 9 : b = 3, b = - 3

The solutions are

b = 0, b = 3, b = - 3

(z - 4)^{3} = 0

55.82 x^{3} - 12 x - 384 = 0

700 (x)^{5} = 210

m^{3} + 2 m + 1 = 0

- 3 x^{3} = 0
