[(x)*x^3+4-7]=24

解

[(x) \cdot x^{3} + 4 - 7] = 24

解

x = 4 3^{3}, x = - 4 3^{3}, x = 4 3^{3} i, x = - 4 3^{3} i

解答ステップ

[(x) x^{3} + 4 - 7] = 24

改良

x^{4} - 3 = 24

x^{4} - 27 = 0

equationを

u = x^{2}

と以下で書き換える:

u^{2} = x^{4}

u^{2} - 27 = 0

解く

u^{2} - 27 = 0 : u = 27, u = - 27

u = 27, u = - 27

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = 27 : x = 4 3^{3}, x = - 4 3^{3}

解く

x^{2} = - 27 : x = 4 3^{3} i, x = - 4 3^{3} i

解答は

x = 4 3^{3}, x = - 4 3^{3}, x = 4 3^{3} i, x = - 4 3^{3} i

z^{3} = 2^{\frac{5}{2}} (1 + i)

4 x (x^{2} - 4) = 0

solvefor x,f=x^3
