一位數(shù)學(xué)教授被一倆時速很快的車撞倒了。警察跑過去問:“先生,您能說出撞您的那輛車的車牌號碼嗎?”
The professor replied,"Well,not exactly,but I do recall that if the number was multiplied by itself,then divided by three,the square root of the answer would turn out to be the original number with the integers reversed.”
教授回答:“嗯,我說不準(zhǔn),可是我記得,如果將號碼自乘,再除以三,然后開方,則平方根正好同原數(shù)的次序顛倒過來。”
