r^6=64

解

r^{6} = 64

解

r = 2, r = - 2, r = 1 + 3 i, r = - 1 - 3 i, r = 1 - 3 i, r = - 1 + 3 i

解答ステップ

r^{6} = 64

equationを

u = r^{2}

と以下で書き換える:

u^{3} = r^{6}

u^{3} = 64

解く

u^{3} = 64 : u = 364, u = 364 \frac{- 1 + 3 i}{2}, u = 364 \frac{- 1 - 3 i}{2}

u = 364, u = 364 \frac{- 1 + 3 i}{2}, u = 364 \frac{- 1 - 3 i}{2}

再び

u = r^{2}

に置き換えて以下を解く:

r

解く

r^{2} = 364 : r = 2, r = - 2

解く

r^{2} = 364 \frac{- 1 + 3 i}{2} : r = 1 + 3 i, r = - 1 - 3 i

解く

r^{2} = 364 \frac{- 1 - 3 i}{2} : r = 1 - 3 i, r = - 1 + 3 i

解答は

r = 2, r = - 2, r = 1 + 3 i, r = - 1 - 3 i, r = 1 - 3 i, r = - 1 + 3 i
