考的不好，一点机经了表心意。

ARGUMENT

47 The owners of the Comquat Cafe evidently made a good business decision in moving to a new location, as can be seen from the fact that the Cafe will soon celebrate its second anniversary there. Moreover, it appears that business are not likely to succeed at the old location: since the Cafe's move, three different businesses--a tanning salon, an antique emporium, and a pet-grooming shop==have occupied its former spot.

ISSUE

A2 Constant innovation and change within an organization are as likely to damage the organization as they are to improve it.

Math

1. d=2^64, d^d=2^P, P=? (我答2^70）

2. Company A has x addresses, Company B has y addresses, Company A combined with Company B, total 3 times of Company A, 问，how many addresses belongs to both Comany A and Company B? （我答y-2x; A交B=A+B-A并B）

3. 一条线段，在-3和-4中有一黑点，问黑点的值，下面有几个选项（我答负根号10）

就这些了，不好意思记不住了，老话说生完孩子傻三年，看来一点不错。

楼主： d=2^64, d^d=2^P, P=? (我答2^7）^这个符号是什么意思？
