4 to the (3x - 6) = 64, you can solve with BASIC MATH! 

I watch these math problems about once a week. Mostly because I forgot some of my math, and it's nice to review some of it. I don't think this instructor is condescending or arrogant. He actually does a good job, and he is very patient. As my skills return, I watch fewer of the lower level math videos. Because means I have moved on for those skills. It's possible that would not have regained those lost skills if I hadn't watched these. Now that I've this level I'm reviewing and relearning my calculus skills, and I'm watching those most of the time now. It is great to be able to sneak in a quick review on a phone at my convenience without being required to sign up for a class. Keep up the good work, I really appreciate these math reviews videos.

Really clear, simple and useful. Thank you, John.

For the people in the comments saying they did this in their head cause it was super easy, that’s not the point of these videos. He gives you the simple one to teach you how to do the hard ones. Like the example 9^x=12, you can’t just solve that in your head. You need to know log exists for that. I now know that x(log9)=log12 so x is approx 1.131. I wouldn’t have known that before this video.

It's sad that these guys that comment who are obviously good at maths cannot reason that you are attempting to teach folk who are not so good or who had a poor teacher when they were at school how tou use different methods. You are not condescending but rather patient and allows anyone who wishes to learn to follow step by step to understand the solution. My only very slight criticism, if I got it right, was your off the hoof example where you substituted 5 for (3x-6)log 4 = 18 as the log of 64. I know you were only using this as an example of logs but students might think (3x-6) = 18/3 ? Having said that I appreciate what you were saying in the example and I applaud your Intentions to smarten up all us thick folk in the use of maths. I apologise in advance if my sole criticism was misunderstood by myself.

I solved in my head. 4 to what power will equal 64? Easy 4 raised to 3rd power is 64. So 3•3 = 9; 9 - 6 = 3; Therefore the answer is x = 3! Yeah; the more we practice solving these problems, the easier it gets (for me anyways)!

Greetings. The answer for X that satisfies the expression for both sides to be equal is 3. To determine the value of X, we express 64 in a form containing base 4 raised to the required exponent to get 64. That is, 4^N=64. What is the value of N? N is 3. Therefore, 64 =4^3. Moving forward, the left hand side and right hand side of the expression have he same base. Accordingly, we can equate the exponents to get 3X-6=3, and 3X=3+6 for 3X=9, and X=3.

This was a cool little problem. Thanks!

The (3x-6) must evaluate to 3 as 64 is 4^3. So, x=3 as 3*3-6 = 9-6 = 3.

Great video for people who aren't as strong at math. There's only one exponent that could result 4×?×?=64, that being 3. The only whole number you can subtract from 6 to get 3 is 9. So 3×?=9. ? Would havet to = 3

My basic math is good. My basic algebra though, a work in progress. ;) But I used some algebra to find x as 3x-6 = 3 and it was easy. And yes, I applied the rule. What you do on one side... I'm sold on this one now. :)

I first knew 64 was 4x4x4 That all I figured. And looked at comments. Now I will watch your video.

I think it would be far more interesting if the problems you post, and show how to solve, had some actual use.

Thank you

Tabletaths must watch the videos by MrHtutirials. What a great teacher.

64 = 4³ And 4 to power of 3x-6 means we have an exponential equation with 4 as the common base. So we get from the exponents, 3x-6 =3, 3x =9. x =3 😅

Hi your maths is great

1:24 This is pretty simple, did it in my head (thanks for the easy ones!) my wife would never figure this out, unfortunately as she is in finance. That being said 4^3=64 therefore, (3*3)-6 =3, and that leaves 4^3, which is 64. You don’t need brute force if you just know some basic multiplication. Sad you offered us to use a calculator for this one.

3x - 6= 3, 3x=9, x=3

I would be asleep inside of 15 minutes if I had this guy for any of my math classes.

4 to 3x- 6 =64 4 to 3x- 6 = 4 to 3 Simplify 4 This becomes 3x-6 =3 3x-6+6=3+6 3x =9 x=3

See i told you i was thick, i meant to write 18/5 where i was criticising your example! 😮

x=3. Took 30 SEC by sight (inspection).

He is in love with himself. He can not stop repeating himself. This is not teaching. It is showing off.

4^3 = 64 => 3x-6 = 3 => x = 3

3. Quite easy.

People should be able to do a problem like this in their head in less than 5 seconds.

This Question is So easy

Do not use calculator. Instead see that 64 is 4^3. Then since 4 is the base on both sides of the equation, both exponents are equal. Therefore 3x-6 = 3, and x = 3.

3 i hope

5 seconds...3...had to be the cube. Thanks for an easy one.

3. I am getting good

you tube maths man.....legend.

X=3 ans

Easy peasy thank you that's why I'm the king of math

If you know, that 64=4^3,the solutionis very easy: 4^(3x-6)=4^3 comparision of exponents leads to 3x-6=3, adding 6 on both sides and we get 3x=9, dividing both sides by 3 leads to x=3.

X=3

Just take log base 4 of both sides.

x=3

X=3 because in a previous video I watched of yours, you showed us how to make the bases the same. Then you're left with just 3x-6=3 3+6=9 then divide by three❤🎉

That took about 10x seconds to solve

X=3....

Four to what power equals sixty four ….Three….Thank you Baby Boomer. FYI Love you content

MS, Crockett, exactly who are you trying to talk down too.

Mr mark please dont blame your teachers. Be honest you are at fault. The teachers that taught me didn't take 20inites to explain such an easy problem..this titor will not vomplete the syllabus. I was an average student but i eorked had to understand and ask questions

I solved it in my head in less than 10 seconds.

Wasted time on a trivial problem.

Tool maybe 10 seconds to solve: answer is 3.
