2. 2x^-4 translates to 2/x^4
Well that is by convention, rules of exponents.

For eg. 5 = 5^1 and 1/5 = 1/(5^1) = 5^(-1)
Similarly

x^-4 = 1/x^4.

There is nothing much I can explain here. Hope you understood.

1. sqrt((5^2)^3)) translates to 5^3 Lets see how the exponent itself can be manipulated. (5^2)^3 = (5^2) * (5^2) * (5^2) (if you don't agree, then stop at this point and spend some more time understanding exponents. (5^2) * (5^2) * (5^2) = (5*5) * (5*5) * (5*5) = 5 * 5 * 5 * 5 * 5 * 5 = (5)^6 At thi...

Well, it depends on the context. The usage great numbers of people is correct when you are referring to multiple sets of numbers. But in this question, none of the remaining answer choices seem to fit. People though collective can be counted. We say many people, not much people. So that rules out al...

That's a decision you got to make. :) But my opinion. Your GRE scores atleast look better than GMAT considering that you are looking at those schools. The only problem with applying with GRE is that schools are yet to release class profiles with GRE scores (right?). So it will be difficult to judge ...

Use the 5 MGMAT guides. They deal with GMAT with a view to addressing those with weak math but you will learn a lot. and a lot of practice.

Also, just to give you some confidence, GMAT math cannot kill you. :-) You will do well.

All the best. And someone on the forum is always available to help.

Well, schools have to accept your score as long as it is within the 5 year period. No question on that. There are 2 sides to this coin according to me. 1 side, you can have scores from the latest format. But on the other, we don't know how the new pattern is going to affect your capacity to perform ...

2 days from the test, dont stress yourself out too much. It is not good. I recommend that you take GMAT Prep prac test, maybe once or twice. Nothing more. Yes, try to finish the test. Simple way of doing that is, if you are not able to get an answer in quant in 2 minutes, leave the question and move...

Sorry to be replying on the mbaMission thread. But I can tell you what they will tell you. LORs from family are a big no-no. Him studying in booth does not make a difference.

2 weeks cannot really change much. But it can strengthen your current levels. One advice I wanna give you is not to put too much effort so close to the exam. You will run out of steam for the actual test. Just take a few prac tests and keep your stamina high for the test. You can take some extra pra...

There are no known problems on the tool.

What do you mean by the "raw score" in the bracket? Raw score is not equal to number of questions right.

Anyway, the tool is fine and please don't compare scores on tests from different companies. Only GMAT Prep has the right algorithm.

Since then have you been working for your current boss? Then No, it's not a problem. But if there is some other person you can go to for the period in between, then you should go to that person. At the end of the day, go to people who will talk (well) about you and are willing to write recommendatio...

Notre Dame and Mendoza have completely different profiles. I think your profile can get you into Notre Dame. I don't know about Kellog cos it's a top 10 school and I am not best placed to say someone will or won't make it. For quant, if you have something else to show such as some extra course work ...
