\(2^{10}*25(25-8)+2^{14}\)
\(2^{10}*25(17)+2^{14}\)
\(2^{10}(425)+2^{14}\)
\(2^{10}(425+16)\)
\(2^{10} (441)\)
Prime factors of 441 are 3 and 7
So, the greatest prime factor is 7

Half of the subjects in an experimentthe experimental groupconsumed
Half of the subjects in an experimentthe experimental groupconsumed large quantities of a popular artificial sweetener. Afterward, this group showed lower cognitive abilities than did the other half of the subjectsthe control groupwho did not consume the sweetener. The detrimental effects were attributed to an amino acid that is one of the sweetener's principal constituents.
Which of the following, if true, would best support the conclusion that some ingredient of the sweetener was responsible for the experimental results?
A. Most consumers of the sweetener do not consume as much of it as the experimental group members did.
B. The amino acid referred to in the conclusion is a component of all proteins, some of which must be consumed for adequate nutrition.
C. The quantity of the sweetener consumed by individuals in the experimental group is considered safe by federal food regulators.
D. The two groups of subjects were evenly matched with regard to cognitive abilities prior to the experiment.
E. A second experiment in which subjects consumed large quantities of the sweetener lacked a control group of subjects who were not given the sweetener.

Re: MBA Resume - Mistakes you can avoid!
Hey guys, I've got a question- what are your thoughts in including links i.e. hyperlinks in B-school CV? For example, I have done various marketing campaigns for my business, some of them include getting online content published on other websites or there are some where other companies (mostly my customers) who mentioned me (and my company) in their website. There are also online publications that I've written as well. So, I am thinking of linking all of these content onto my B-school CV. I wasn't going to list down a bunch of links but am writing it this way (for e.g.):
Created content marketing campaigns with [X] which led to increased brand awareness and inbound through website
Featured on [X] at [customer Y's] website
[X] would include where I'd include the hyperlinks.
Anyone care to share their thoughts?

Can anyone please explain the answer. Also, is there any rule that says "hopefully" is almost always wrong in GMAT?
MANHATTAN REVIEW OFFICIAL EXPLANATION:
Hopefully is an adverb. It can be used in a sentence such as: The skier looked hopefully at the sky in search of snow. It cannot be used as a replacement for I hope, we hope or it is hoped. Eliminate A, C and D. It is not correct to say pollute such as aerosol cans do. Eliminate E. The correct answer choice is B.

Area of Parallelogram - base * height
hence if area of EBFD is 3, that means that base is 3 and height is 1 ---> 3*1=3
simiralry area of AECF is AECF, meaning base is 2 and height is 1 ---- > 2*1 =2
Area of rectangale base is 2+3 =5 and height is 1, so 5*1 = 5

Question REPHRASED: Does Jack > 1.67* David?
Statement 1: The number of pens David has is 60 percent of the number of pens Jack has.
David = 0.6 * Jack
i.e. Jack = (1/0.6) David
i.e. Jack = 1.67 David
i.e. Answer to the question is NO as Jack is not greater than 1.67*David, It is Equal to 1.67*David hence

Re: Instead of blaming an airline accident on pilot error, investigators
nocilis wrote:
Instead of blaming an airline accident on pilot error, investigators should find out why the error was made by analyzing airplane design, airline management, and pilot-training programs. For only then can changes be made to ensure that the same type of error does not recur and cause another accident.
Which of the following is a presupposition of the argument above?
(A) Pilot error is not a contributing factor in most airline accidents.
(B) Airline companies themselves should be the agents who investigate airline accidents.
(C) Stricter government regulation of airline companies will make air travel significantly safer.
(D) Investigators of airline accidents should contribute to the prevention of future accidents.
(E) Most pilots who make errors in flying will repeat their errors unless they are retrained.

(A) Pilot error is not a contributing factor in most airline accidents.

(C) Stricter government regulation of airline companies will make air travel significantly safer.
(D) Investigators of airline accidents should contribute to the prevention of future accidents.
(E) Most pilots who make errors in flying will repeat their errors unless they are retrained.
In the second sentence, notice the use of "For" only then ... It plays the role of "because". It marks a premise, not a conclusion.
Premise:
Only when one finds out why the error was made by analyzing A, B and C, can changes be made to ensure that the same type of error does not recur and cause another accident.
Conclusion: Instead of blaming an airline accident on pilot error, investigators should find out why the error was made by analyzing A, B and C
What is the gap in the argument? The premise tells you that only when you do X, will future accidents be avoided. The conclusion says that investigators should do X.
The assumption is that investigators should help in preventing future accidents. That is why the author asks them to do X.
Add this assumption to the argument and see if it makes sense:
Only when you do X, will future accidents be avoided.
Investigators should help in preventing future accidents.
So investigators should do X.
Makes sense now, right? So (D) is correct.
As for (E),
The argument asks investigators to analyse the training program, not retrain the pilots. Nothing has been said about pilots needing retraining. Perhaps analysis of training program will reveal that pilots are taught in a different way whereas airplane design shows it differently etc. Then it is a judgment call on whether pilots need to be retrained or airplanes need to be redesigned. All I mean to say is that perhaps pilots don't need to be retrained. Our argument certainly does not assume it. IT asks us to analyse multiple things to avoid errors in the future.
