69=c^3

解答

69 = c^{3}

解答

c = 369, c = - 369 \frac{1}{2} + 369 \frac{3}{2} i, c = - 369 \frac{1}{2} - 369 \frac{3}{2} i

求解步骤

69 = c^{3}

交换两边

c^{3} = 69

对于

x^{3} = f (a)

解为

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

c = 369, c = 369 \frac{- 1 + 3 i}{2}, c = 369 \frac{- 1 - 3 i}{2}

化简

369 \frac{- 1 + 3 i}{2} : - 369 \frac{1}{2} + 369 \frac{3}{2} i

化简

369 \frac{- 1 - 3 i}{2} : - 369 \frac{1}{2} - 369 \frac{3}{2} i

c = 369, c = - 369 \frac{1}{2} + 369 \frac{3}{2} i, c = - 369 \frac{1}{2} - 369 \frac{3}{2} i

x^4+8x^3+9x^2-28x+10=0

x^{4} + 8 x^{3} + 9 x^{2} - 28 x + 10 = 0

x^{50} = 0.01

x^3-3x^2-44x+2222=5.88

x^{3} - 3 x^{2} - 44 x + 2222 = 5.88

0.0012 = x^{3}

x^4+2x^3-6x^2+3x=0

x^{4} + 2 x^{3} - 6 x^{2} + 3 x = 0
