(x-7)^4=625^7

解

(x - 7)^{4} = 62 5^{7}

解

x = 6254244140625 + 7, x = - 6254244140625 + 7

+1

十進法表記

x = 78132, x = - 78118

解答ステップ

(x - 7)^{4} = 62 5^{7}

(g (x))^{n} = f (a)

の場合, n は偶数, 解は

g (x) = n f (a), - n f (a)

解く

x - 7 = 4 62 5^{7} : x = 6254244140625 + 7

解く

x - 7 = - 4 62 5^{7} : x = - 6254244140625 + 7

解答は

x = 6254244140625 + 7, x = - 6254244140625 + 7
