What is the value of n
(1) n⁴=256
(2) n³>n²
网考网参考答案：C
网考网解析：
alone is insufficient because n could equal either 4 or-4. (2) alone is insufficient, because although it tells us that n＞1, it does not give a value for n. If the statements are combined, n=4 is the only solution to the stated criteria. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
