I just want to let you know that I was stuck on 3 GMAT Exponent problems for 2 days. After watching this video I noticed ways to manipulate the numbers and solved 2/3. Thanks a lot. The last one is more ticky. Your video got me halfway through it,
Courtney Stokes Glad this helped! Study hard and let me know how else I can be of service.
Dominate the GMAT Thanks. I figured that last problem when I got to work so Im 3/3 thanks to your help.
PLEASE YOU SEND ME SAMPLE GAMT ENGLISH AND MATHS pdf or word doc. QUESTION IN MY EMAIL

I love the way you tell the whole story. The intonation, the rhytmm, dan the tempo were perfect. Thank you so much..!
Hi Brett,
Thank you very much for providing such an informative and easy-going walkthrough of exponents for GMAT. I also appreciate how kind and positive you seem to be. I have found multiple of your videos really helpful towards the GMAT, so I appreciate your content!
Best wishes,
John
Thank you for taking the time to comment, Gregory. I'm glad you've resonated with my teaching style. Best of luck to you on the GMAT and let me know if there's anything else we can do to help!
Probably the only type of quant question I had difficulty with, this was a huge help, thanks a lot!
It's nice when you've gotten your weaknesses down to just a few. Glad this video cleared some things up for you!
This was a wonderful example and explanation. You are like a magician. Actually you did a good job of using the laws of exponents and simplifying terms.
I appreciate that. Glad it helped. Good luck with the rest of your prep and let us know how else we can help!
This took me about 15-20 seconds, tops! That way you said that the problem was difficult at the beginning of the video made me doubt myself for a while.
The GMAT thinks it's difficult, so that's a good sign for you!
Are you sure this question is difficult in terms of GMAT?Thanks for videos I am constantly following your videos .Your videos makes the problems solve it in a most easiest way.Helps us to gain confidence.
Yes, this is considered a difficult question because there is a variable as an exponent, and because quite a bit of manipulation using exponent rules is necessary to solve it. I'm glad you've been finding my videos helpful! I know you'll love my comprehensive GMAT Prep course even more, if you decide to move forward with it.
that is a beautiful painting behind you! love it =)
Thank you! Glad it added to the video for you 😀.
A good approach to that problem would be to think « I’m looking for the value of m », so in the right side of the equality, you can try to eliminate the 1/2*.. and actually this is why the 1/4.. is here, and without any calcul; you just see that 2 * 2^35 = 2^36. And in the Left side you can see that 1/4 ..
You going to have 2^36, so you have 1/5 on both part with the 35 on top of m.
Once again, thank you so much for your videos. This was extremely helpful.
Amazing really helpful
Glad to hear it. Good luck and let me know how else we can help!
When you got to the step where you had one fraction equal to another fraction, can you just flip both fractions and work the remaining steps with whole numbers?
Yes. Since the numerator is 1 in all of the fractions, you're really just concerned with the denominators anyway. So yeah, "flip them" and keep working with whole numbers.
Thanks Sir!
You're welcome!
Amazing trick sir.. Thank you
You're welcome!
Wow! I like you already thank you very much
You're welcome, Carole. I'm glad you found us. Good luck and let me know how else we can help!
Thank you so much Brett please clarify for me the difference between 4^3^3 and(4^3)^3 if any
@@caroleg1997 Those are effectively the same, though the second variation is the preferred notation.
Thats the worst way to write 8 that I've come across in my life 😂😂😂😂
amazing! Thanks!
This question is less then 10 sec if we use log on both side
Can you do that without a calculator?
@@dominatethegmat i done that without calculator. By just log properties and then comparing L.H.S and R.H.S you should also try once
@@gamingpur2008 That's what I thought. Remember that you can't use a calculator on the Quantitative Reasoning section of the GMAT, so make sure you have other ways of solving questions like this.
I am so scared of GMAT q's but this video helped
Awesome, I'm glad it helped! My comprehensive GMAT quant course will give you even more confidence: www.dominatethegmat.com/video-purchase/full-gmat-quantitative-course/. Enjoy!
What level problem is this? I solved it under 30 secs
That's awesome! It sounds like you have a good grasp on these types of GMAT algebra questions, then.
Great stuff!
Thanks Lincoln, glad you found it helpful!
Hi
Nice problem..However I just want to ask one thing regarding the approach to this problem..When I read the question and glanced through the options... I could quickly guess the 'M' would be odd... Am I right?PLease reply.
It depends. What logic led you to conclude "m" must be odd? I'm not quite sure how you'd draw that conclusion just by looking at it, other than the 5 in 1/5 being odd while the 4 in 1/4 is even. Perhaps you could use that as a guessing reason if you didn't know how to actually calculate it, but I don't see any obvious underlying math reason (other than understanding how the exponents themselves work) that you could quickly discern when you first look at it.
Wow, awesome!
Thanks! Glad you found it helpful.
Kickass problem!
Is this a 700+ question?
It's safer to categorize questions as "Easy," "Moderate," or "Hard" as the GMAC does in its own Official Guide. This would be a "Hard" question -- meaning it's somewhere in the mid- to upper-600 or 700+ range.
That was awesome
Glad you found it helpful!
took me 7 sec
Congrats. That's awesome!
I think you’re making this question seem way harder then it needs to be, it’s pretty basic. 4^18 has no factors of 5, so all of your factors of five come from 5^m. 10^35 has 35 factors of five, so m must equal 35. It’s really that simple. You don’t have this kind of time on the GMAT, so I’m confused why this video is so long.
Thanks for sharing your approach! (BTW, a lot of what I'm trying to do in this video is teach people underlying exponent rules that they can apply to future questions.)
u r really super
Thanks!
Which level of question is this?
Upper 600's, I'd say.
May be it's easy one
Solved within 10 sec
ur a genius
What the frick, it took less than 30 seconds. So this is possible for high schoolers too, interesting.
My brain hurt
Haha, but did you learn something?!
m=35
Just takes 20 seconds
Very bad explanation!
