  • I thought that if you get a yes and no answer for a statement, it would be insufficient! Why is "A" sufficient? Please help!

  • "Vedic Math Calculator" Try any number and find tricks to solve it @ maths.kuchnaya.com

  • Question is good BUT there cannot be conflicting answers in DS questions...if you knew the GMAT well you wouldn't have made this mistake. Thanks for the effort anyways.

  • state if 'n' is a positive integer in the question plz.!

  • Nice job, jerk off. You obviously don't know shit about the GMAT if you're explaining a problem such as this one. Like dreamtheater states, you cannot have conflicting answers on the GMAT. And your logic and reasoning in the video are way off. So way to go, champ.

  • This video is incorrect. On the GMAT, the two sub-prompts will NEVER conflict each other. Sub-prompt 1 results in 64 being the only solution, while sub-prompt 2 results in 27 or -27 being the only solutions. This situation will never happen on the GMAT. This concept is something that is every important to learn in order to solve some of the most complicated questions.

    Beyond that, sub-prompt 2 has two solutions -- 27 and -27. Therefore, your solution is incorrect. The answer should be A.

  • love your videos!

  • cube root of -27 is -3..how do you know N is +ve?

  • Question:  Where do you get ABCDE from?

  • very good. I like such teaching
