I've tried to fault where I got it wrong here aside the other value of x but I couldn't. The mathematical blunder remains elusive.
Please someone help out.

But the disadvantage of that plot is that you can't see more than 4 dp or so.
So you will take it to another plot to see five dp and approximate the sixth.
Or better use Lambert W if you are fortunate it will lead you to omega function that have constant special value (like our special angle in trigonometry you don't need program for such just substitute you will get your exact answer ) otherwise you program it. And get your exact value

Here is the correct plot.
I don't know if you understand what I saidvand another fault is that you interval is to wide
Maybe you can use rage of values of x as 0.1, 0.2, 0.3,0.4.........
And also you need to plot on a graph of equal dimension

You made x a constant x us not a constant it is a straight line graph with slop of 1 that is start from the origin a pass the center dividing the rectangular plane into two triangle

Mrshape don't worry. I'll still do another one next month as I'm thinking of making this a monthly thing. Be sure to be on the look out and also be fast with your solutions. You're a great guy!

Thanks boss.
Look forward to taking part in it.

Thanks, man. I wished you won yourself, because you've been championing stuff like this. But as our people would say 'one's time awaits him', you'll also be rewarded in due course. Keep doing what you know best to do.

Very encouraging.

rejoice4eva:
Hypocrisy is when you see things and you are saying the opposite
Hypocrisy is when you are complaining secretly, and you are crucifying the one complaining openly.
Hypocrisy is when you are crucifying some one for doing something, and you are praising some one for doing the same thing
I can go on and on. Give your own description
But hypocrisy is evil and any society bedeviled by it will find it difficult to move forward.
Can Nigeria ever be truthful and frank for once ?

Hypocrisy is when you tell people no gathering stay at home. And you went for a burial (funeral)

Here are the winners and the time stamp showing when they sent in their responses. For those of you that sent me mails twice, I did't pick you because I mentioned earlier that it attracts disqualification. I initially intended to pick 5 winners but had to pick one more person.This didnt follow the rule of the fastest but the one who came close to answering question 1.

If I tell you say this thing no pain me an na lie.
Mime came in 9:38am
And that shape I solved it here in this forum about 4 days ago after much begging for the solution.
When there is shape question their will be calling Mr everywhere but when it is money involved now.
No one mentioned me for good 12 hours before I knew

Yeah, these are used to obtain the zeros of the func4ion before plotting it on a single curve. I have posted the solution here. I will not post the newton-raphson one because I have already said one of the winners will post that.

Alright let's wait for them,
Although I can do Newton very well.
But I don't usually consider it as a full numerical value

Where is the graph?Wolfram alpha is free. There are other tools like mathcad that is not a program but a calculation software you can use to arrive at the answer too.

OK I will send it here

Better. I'm also completing that graphical solution now and may post it here if people want.

I did they graphical to get my solution too.
Because I don't have paid wolfram alpha.,
That's I I got my two values for my solution
The constant value of omega of that function gave one solution.
So I use graph yo evaluate and zoom.
Anyway it was a nice challenge.
What I want to learn from you is how to get the omega value without program

Yours is also dubious. You people usually do not complete the proof to the Lambert W function. I need to do a lecture on that for a fee on this forum.

When you do the lecture mention me.

So why were you arguing?The problem is that you guys don't know how to complete the solution using the Lambert W function. The Lambert W function will give you the two numbers x=2 and x=0.154953466 when carefully applied.

Alright.
But the answer we usually leave as a function or use programing to get the numerical value.

I was typing a response(one meant for only mathematics intellectuals) to your earlier message on how flawed your workings were until I saw this so I had to stop. Please check my previous message after the deadline passed. This question has two solutions i..e x=2 or x =0.155.Substitute both numbers into the equation and see what you have. I can provide you a full working of these solutions according to Newton-Rahpson method if you want to learn. I will even show you calculations on how i arrived at my test values . In your solution, (-1/ln2)/(-2ln2) suddenly gives 2 instead of 1/2ln4. I am now thinking you must have copied this from somewhere online.

Oh my fault there I downloaded the wrong solution I made two solutions that day

I should be the one teaching you about Lambert W functions. I tried using this to solve that question later in the years and didnt still arrive at the beautiful answer I got using the Newton-Raphson method. The solution x=2 is just one root of the equation 2^(2x)-8x=0. The other one is 0.155. Besides, The last two or the lines of your Lambert W solution clearly shows it is dubious.(

Choose for yourself which is more accurate

0.155 is not close to the answer.
Substitute my answer and yours into the equation and see which will give you better result
