Does the decimal equivalent of , where p and q are positive integers, contain only a finite number of nonzero digits?(1)p > q (2)q = 8
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. D. EACH statement ALONE is sufficient. E. Statements (1) and (2) TOGETHER are NOT sufficient. Answer: D
题目中“contain only a finite number of nonzero digits”是什么意思?是指包含一个非零有限小数,还是一个有限小数且此有限小数的任何一位数字都不为零?如果是第二种解释的话,那答案D就不对了,因为如果p=81,q=8,那么 =10.125,有一位数字是零。
