The square root and the cubic root of the dielectric constants are linearly related to the volume ratios 介电常量的二次及三次方根与密度成线性关系。
" personally , i believe most people can do it but i have also a high - speed mind . my brain works sometimes very , very fast . “我相信大多数人都能算出一个200位数的13次方根,只是我的速度稍快一些。我的大脑有时运转得相当快。 ”
Lemaire then took just over a minute to identify two quadrillion , 397 trillion , 207 billion , 667 million , 966 thousand , 701 as the 13th root 而勒麦尔只用了一分多钟的时间就算出了这一长串数字的13次方根,答案是2397207667966701 。
