破解技巧1:对于一些新颖的选择题,依据题目的特点,选择特殊的数值、特殊点、特殊的数列,也许能快速获得正确答案.这可称为特值探索,快速取胜.技巧解读特值有检验、尝试的作用,有利于引导和发现巧妙解法.例1在右边的数阵里,每行、每列的数依次均成等比数列,其中a_(22)=2,则所有数的乘积为A.512 B.256 C.128 D.64难度系数0.60解答过程由于答案为确定的数值,所以取数阵里所有的数为2,得其乘积为2~9=512.选A.
Crack Tip 1: For some novel multiple choice questions, depending on the characteristics of the topic, select special values, special points, special series, may be able to quickly get the right answer. This can be called special value to explore, quickly won. There is a test, the role of trying to guide and find clever solution. Example 1 in the right array, each row, the number of each column are equal geometric sequence, where a_ (22) = 2, then all the numbers The product is A.512 B.256 C.128 D.64 difficulty coefficient 0.60 solution process Because the answer is a certain value, so take all the numbers in the array of 2, the product of 2 to 9 = 512. Select A.
