z^7+1=0

z^{7} + 1 = 0

z = - 1

Solution steps

z^{7} + 1 = 0

Move

1

to the right side

z^{7} = - 1

For

x^{n} = f (a)

, n is odd, the solution is

x = n f (a)

z = 7 - 1

7 - 1 = - 1

z = - 1

z^{9} - 10 z^{6} + 17 z^{3} - 8 = 0

x^{4} + 20 x^{3} + 228 x^{2} + 1384 x + 3020 = 0

x^{6} - 16 x^{3} + 64 = 0

4 x^{3} - 30 x^{2} = 0

(x - 1.5)^{4} = 1 0^{- 8}
