solvefor a,54=a^4

解

解く

a, 54 = a^{4}

解

a = 4 3^{3} 42, a = - 4 3^{3} 42, a = 346 i, a = - 346 i

解答ステップ

54 = a^{4}

辺を交換する

a^{4} = 54

equationを

u = a^{2}

と以下で書き換える:

u^{2} = a^{4}

u^{2} = 54

解く

u^{2} = 54 : u = 54, u = - 54

u = 54, u = - 54

再び

u = a^{2}

に置き換えて以下を解く:

a

解く

a^{2} = 54 : a = 4 3^{3} 42, a = - 4 3^{3} 42

解く

a^{2} = - 54 : a = 346 i, a = - 346 i

解答は

a = 4 3^{3} 42, a = - 4 3^{3} 42, a = 346 i, a = - 346 i
