Yeah too much steps, could find the prime factor of 15, which are 3 and 5. Now 759325 = 3373 *25 and 5^2= 25. Thus, K=2. Substitute into the equation and you'll get 1, which is the answer.

It's just mindblowing the clarity that you have when explaining

I'm impressed by your level of speaking fluency and clarity, congratulations!!! May I ask something ? . Which is the most practical way to detect if a question will take too long to be answered? Are there any hacks or shortcuts to know this? Thanks!

After seeing all of your GREAT explanations (thx 4 that), I only have one question, and I'm afraid is kind of a dumb one (lol). Last problem, the one with the equilateral triangles... The 15 factorial (15!) was 15 x 14 x 13. My question is: Doesn't the factorial (!) mean 15 x 14 x 13 x 12 x 11 x 10 and so on til 1? I mean, how do you know that you needed to stop at 13? Thanks

This person has a horrible voice. I don’t know why they chose her to speak. Thanks anyway. K. L.

Haha, loved this!

Love this teacher !

THANKS ERIKA YOU ARE AN AWESOME TEACHER!! ALL THE ADVICES AND ANECDOTES WHERE REALLY USEFUL!!

Do you have for PhD?

How do you know the questions in the 500 and 700

Thanks Magoosh !

Thanks Erica and Magoosh !

Thanks!

In the quant section, is there a protocol for doing rough work in quants?

Thanks for the interview! Really thoughtful and inspiring!

Thanks Magoosh and Kevin !

Thanks Magoosh and Kevin ! Till you explained, I did not notice the error. Thanks for pointing out this subtle difference !

I was just like where's that old GMAT monster who got 770 why there's no videos , finally i found one !

Very helpful 🩵🌹

Thank you this information was so very helpful 🔥🔥🌅🌹🌹👍👍

Thank you for providing details to look for information that’s provided in the passage 🌷🌿👍🩵

Thank you for sharing 🩵🩷🩷🌅🌹👍

I'm sorry but could you help me? I can't see my mistake I did the following (X+1)/A + X/B = 1 B(X+1) +AX = AB BX + B + AX = AB X(A+B) = AB - B Answer: X = (AB-B)/(A+B) OR B(A-1)/(A+B)

It was an insightful meeting. Tnx

I have a feeling less people might have missed this question (or spent less time on it) if it was more clear in question 1 that S does not equal 10 at the start of the algorithm instead of 12. The way the question is worded can make it seem that way. If the question had instead said: "When a output value of S=10 is first reached, P has a output value of... (Answer choice A,B,C,D,E)" It would be more clear. Maybe that's only my impression because I had not yet been exposed to this kind of problem. Maybe the question was interpreted correctly by others in this way more often than not. I can't really say. Does anyone else have an opinion?

😊

My friend is phlegmatic

C

does this strategy applicable to gre RC

Great information 🎉

Great questions! Thank you for putting this together.

This was insightful!

dopo quanto tempo saranno disponibili i risultati?

What determines what is best?

As a competent math student, I was able to answer all the questions correctly in no time. Are GMAT math problems really at that easy of a level?

Thank you for the video it would be very helpful for me

this was useful thanks

Did he use calculator for quants?

❤❤❤

When will we have classes and study plans for focus

Thank you for the share 🫡

Thank you Jack, now I feel like GMAT is within my reach! :)

thanks for this video!!!!!!!!!!!!!! so good

Thank you😅

Thank you Erika! I had one question. Is there any other way to solve the hard Magoosh example problem without the table if we translate each of the statements into equations?
