n^4+15=38

解

n^{4} + 15 = 38

解

n = 23, n = - 23, n = 23 i, n = - 23 i

解答ステップ

n^{4} = 23

equationを

u = n^{2}

と以下で書き換える:

u^{2} = n^{4}

u^{2} = 23

解く

u^{2} = 23 : u = 23, u = - 23

u = 23, u = - 23

再び

u = n^{2}

に置き換えて以下を解く:

n

解く

n^{2} = 23 : n = 23, n = - 23

解く

n^{2} = - 23 : n = 23 i, n = - 23 i

解答は

n = 23, n = - 23, n = 23 i, n = - 23 i
