1.what is the greatest whole number such that the sum of 7
and the product of 3 and that whole number is less than 32?
a.10 b.9 c.8 d.7 e.6 答案是C
说实话这题我连题目都不太懂，有个整数是7的和，3的积且小於32?????
2.For all numbers p and q, p的n次方 = 2p - 1 and q* = 2q,
then (2的n次方)(3*) has the same value as
a.5* b.6* c.9* d.10* e.18*
恩~这题完全不懂~我想用指数对数解~但忘记怎麽用了XD
以上两题~感谢解答Orz
