x and y are positive integers. If x^(4) + y^(4) + x^(2) y^(2) = 481 and xy = 12 then what is the value of x^(2) - xy + y^(2) ?
Integers include all whole numbers and negative numbers. 'Integer' is a Latin word which means 'whole' or 'intact'. This means integers do not include fractions or decimals. Let us learn more about integers in this article.
A. 9 B. 45 C. 91 D. 90 E. 10 相关知识点: 试题来源: 解析 D 小于100的正整数一共有99个,在小于100的数中最大的平方数是92=81,因此在100以内共有9个数是完全平方数,它们分别是数字1～9的平方,那么不是平方数的数一共有99-9=90,所以D为正确答案。反馈 收藏 ...
