第三道题，请注意2的次方的个位数： 2^1=02，2^2=04，2^3=08，2^4=16，2^5=32，2^6=64，2^7=128，2^8=256，以此可总结规律2的次方个位数一直以2，4，8，6的顺序一直循环。2的100次方，100可以被4正除，所以个位按照顺序可知道是6，另外可知3的101次方等于2的100次方加上5（2+3），4的102次方等于3的101次方加上7（3+4），，所以可得到个位和的等式，6+（6+5）+（1+7）得出25，只取个位数就是5啦~~~~~

另外两道题我也不明白为什么了，英台知道答案了麻烦告诉俺们一声啊。

感谢MM能打这么多字，但是还有点不明白 3^101=2^100+5  这个还是没搞明白，麻烦你再解释一下好吗，脑袋就是比较木的说

第二道题，143除以7余3，所以转化为求3的89次方除以7。3的89次方分解为3X3的88次方，再推出等于3X3的（2乘以44）此方，3的平方9除7余2。则题目化为3×2的44次方。而后指数继续分解为3x（2的3次方）的14次方x 2的平方，2的三次方为8，余1。则最后分解为为3×2的平方×1的14次方。可见为3×4＝12。则余5。因为俺不会打这些指数，所以叙述可能有些繁琐，不过此题还是主要指数分解，应用了(aⁿ)^m＝a^nm
这个公式，英台自己琢磨便可得出答案。

俺还没有报名呢，计划6月底考试，可现在刚从数学看起，语法和逻辑都没有碰呢，不知到来及来不及：（

“所以转化为求3的89次方除以7”不明白这个是怎么转化的，能再解释一下吗？（看来不是一般的笨，MM忍耐一下吧）

我还有两个礼拜就考了,一点谱都没有.作文还没开始看,来得及么?

另外,英台,你应该只比我晚3天考吧,那最后这十来天应该怎么复习呢?能共享一下你的复习计划么?

还有,那个送分的5个学校应该是要到哪去查代码啊?

我现在是一头雾水啊啊啊~~

DengMM不好意思，由于各种原因，暗不得已把考试推迟了一周现在是21号，怎们样，这日子，炫吧！

计划，我也没什么好的计划，天天学习也不是很有规律，打算把OG做完，然后开始GWD，最后PREP了。MM呢？

姑娘们，怎么都不露面了？都在用功吧~~

我不知道你在美国还是加拿大， 如果是在美国的话，旧金山的golden gate university的会计硕士不用gmat.  私利大学, 但是会计不错, 在4大的口碑很不错.

kellyfang

请问gmat可以考几次？ 考的次数多了，报考好的学校会不会有困难？

justoneway

例如3^3就等于2^2加上2再加上3，而4^4次方就等于3^3次方加上3再加上4，规律总结就是(a+1)^(n+1)=a^n+a+(a+1)

justoneway

而第二道题，应为143除以7余数是3，所以143^89可以转化为3^89，应台品味品味就知道了：）

justoneway

kellyfang,多谢你提供的信息，但是我还真没概念，像这种私立学校一般情况下学费估计要多少银子啊？至于gmat可以考几次，好像没有听到有限制次数的，不过感觉如果能一次取得理想成绩总比反复几次要好些了：）

谢谢Justmm，偶再想想~~

55. Low-income families are often unable to afford as much child care as they need. One government program would award low-income families a refund on the income taxes they pay of as much as $1,000 for each child under age four. This program would make it possible for all low-income families with children under age four to obtain more child care than they otherwise would have been able to afford.

Which of the following, if true, most seriously calls into question the claim that the program would make it possible for all low-income families to obtain more child care?

(A)       The average family with children under age four spends more than $1,000 a year on child care.

(B)       Some low-income families in which one of the parents is usually available to care for children under age four may not want to spend their income tax refund on child care.

(C)      The reduction in government revenues stemming from the income tax refund will necessitate cuts in other government programs, such as grants for higher education.

(D)      Many low-income families with children under age four do not pay any income taxes because their total income is too low to be subject to such taxes.

(E)       Income taxes have increased substantially over the past 20 years, reducing the money that low-income families have available to spend on child care.

B     Although the money is to be in the form of a refund that could be spent however the family wished, it is the availability of additional money that is the point of the claim.  .

无法理解B.

无法理解B.

既然这个programe的目的就是improve children care,如果说Low-income families 不把这笔钱用于children care.这项programe不就没有达到目的 吗?

姑娘们，帮忙看看阿！

看红字部分,是POSSIBLE,B是POSSIBLE的,只是没用在improve children care,而D是连那个REFUND都没有.
