解

a^{4} = 5 (4) - 1

解

a = 19, a = - 19, a = 19 i, a = - 19 i

解答ステップ

a^{4} = 5 (4) - 1

簡素化

5 (4) - 1 : 19

equationを

u = a^{2}

と以下で書き換える:

u^{2} = a^{4}

u^{2} = 19

解く

u^{2} = 19 : u = 19, u = - 19

u = 19, u = - 19

再び

u = a^{2}

に置き換えて以下を解く:

a

解く

a^{2} = 19 : a = 19, a = - 19

解く

a^{2} = - 19 : a = 19 i, a = - 19 i

解答は

a = 19, a = - 19, a = 19 i, a = - 19 i
