If n is a positive integer and m=6.25×10ⁿ what is the value of n
(1) 500＜m＜5,000
(2) m＜6,250
网考网参考答案：A
网考网解析：
alone is sufficient because the only value for m that meets the stated conditions is 625, which means that n=2. (2) alone is insufficient because m could be equal to 6.25, 62.5, or 625. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
