※ 引述《little444 (胖妞妞胖)》之銘言：
A student took (the positive square root)...A of
(the sum of a positive number and 1)...B ,
and then divided the result by 4.
If the answer he obtained was 6, then this positive number
could be-----------Ans: 575
: 可以解釋一下題意嗎
一個學生 (將一正整數 和 一的和)...B (開平方根取正數)...A
然後再將該值除以四 結果是六
求該正數
列式:
√(x+1) / 4 = 6
X=575
