Talk:127

oh look 127 has the same digits as \(2^7 - 1\). in fact it's the only three-digit number \(abc\) that is equal to \(x^y - z\), where \(xyz\) is a permutation of \(abc\)

in addition, \(736 = 3^6 + 7\) and \(347 = 7^3 + 4\) are the only solutions for \(x^y + z\) FB100Z &bull; talk &bull; contribs 18:11, January 4, 2014 (UTC)
