※ 引述《little444 (胖妞妞胖)》之铭言:
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
: 可以解释一下题意吗
一个学生 (将一正整数 和 一的和)...B (开平方根取正数)...A
然後再将该值除以四 结果是六
求该正数
列式:
√(x+1) / 4 = 6
X=575
