solvefor x,x^3=10^6

解

解く

x, x^{3} = 1 0^{6}

x = 100, x = - 50 + 503 i, x = - 50 - 503 i

解答ステップ

x^{3} = 1 0^{6}

1 0^{6} = 1000000

x^{3} = 1000000

x^{3} = f (a)

では, 解は

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

x = 31000000, x = 31000000 \frac{- 1 + 3 i}{2}, x = 31000000 \frac{- 1 - 3 i}{2}

31000000 = 100

簡素化

31000000 \frac{- 1 + 3 i}{2} : - 50 + 503 i

簡素化

31000000 \frac{- 1 - 3 i}{2} : - 50 - 503 i

x = 100, x = - 50 + 503 i, x = - 50 - 503 i
