19s^3=1

解

19 s^{3} = 1

解

s = \frac{1}{3 19}, s = - \frac{1}{2 3 19} + \frac{3}{2 3 19} i, s = - \frac{1}{2 3 19} - \frac{3}{2 3 19} i

解答ステップ

19 s^{3} = 1

以下で両辺を割る

19

s^{3} = \frac{1}{19}

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}

s = 3 \frac{1}{19}, s = 3 \frac{1}{19} \frac{- 1 + 3 i}{2}, s = 3 \frac{1}{19} \frac{- 1 - 3 i}{2}

3 \frac{1}{19} = \frac{1}{3 19}

簡素化

3 \frac{1}{19} \frac{- 1 + 3 i}{2} : - \frac{1}{2 3 19} + \frac{3}{2 3 19} i

簡素化

3 \frac{1}{19} \frac{- 1 - 3 i}{2} : - \frac{1}{2 3 19} - \frac{3}{2 3 19} i

s = \frac{1}{3 19}, s = - \frac{1}{2 3 19} + \frac{3}{2 3 19} i, s = - \frac{1}{2 3 19} - \frac{3}{2 3 19} i

グラフ

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

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

(x^2-x-3)^2-x^3=17

(x^{2} - x - 3)^{2} - x^{3} = 17

(2x^2-5)^2=39+10(2x^2-5)

(2 x^{2} - 5)^{2} = 39 + 10 (2 x^{2} - 5)

z^{5} = 14
