x^8=10^{72}

解

x^{8} = 1 0^{72}

解

x = 1000000000, x = - 1000000000, x = - 1 0^{18}, x = - - 1 0^{18}, x = - 1 0^{36}, x = - - 1 0^{36}, x = - - 1 0^{36}, x = - - - 1 0^{36}

解答ステップ

x^{8} = 1 0^{72}

equationを

u = x^{2}

と以下で書き換える:

u^{4} = x^{8}

u^{4} = 1 0^{72}

解く

u^{4} = 1 0^{72} : u = 1 0^{18}, u = - 1 0^{18}, u = - 1 0^{36}, u = - - 1 0^{36}

u = 1 0^{18}, u = - 1 0^{18}, u = - 1 0^{36}, u = - - 1 0^{36}

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = 1 0^{18} : x = 1000000000, x = - 1000000000

解く

x^{2} = - 1 0^{18} : x = - 1 0^{18}, x = - - 1 0^{18}

解く

x^{2} = - 1 0^{36} : x = - 1 0^{36}, x = - - 1 0^{36}

解く

x^{2} = - - 1 0^{36} : x = - - 1 0^{36}, x = - - - 1 0^{36}

解答は

x = 1000000000, x = - 1000000000, x = - 1 0^{18}, x = - - 1 0^{18}, x = - 1 0^{36}, x = - - 1 0^{36}, x = - - 1 0^{36}, x = - - - 1 0^{36}
