- A great exponential equation! SAT 2020
If you're reading this ❤️.What do you think about this problem?
Hello My Friend ! Welcome to my channel. I really appreciate it!

The SAT does not even test logarithms and this would be multiple choice question.
I got the same answers through slightly different means. But why do you label this as "the hardest SAT problem?" I have never seen the SAT ask a question that uses the Lambert W function.
The SAT does not use a lambert W function. Also, if this was on the SAT, everyone would get desmos so this would be incredibly easy. Just graph it lmao.
C'è sempre una prima volta no?
Exactly this is not an SAT type question using the W function.
I really like these videos!! Thank you for your inspiring content, it helps me a bunch
The explanation is great but takes a lot of time. I believe the SAT test is multiple choice. so you could easily make up a table of x, x^4 and 3^x and use a scientific calculator to find that the correct value of X lies between 1&2, 7&8 then choose the closest answer. It would take a shorter time and no higher math needed.
At the time of 2:12, I am curious, how can you divide by "x"? How can you assume that "x" is not equal to zero?.
Because if you insert zero, you get 0^4 = 3^x, solve it and you get 0=1. X can’t be zero
@@TheFrewah,
and is it no longer necessary to mention that check within the solution process .
@@keescanalfp5143 Yes, such checks should be made. Division by zero is a sin
Who is Lambert? (No, I didn't "google" it and I'm not going to.)
Mr. Lambert enters the room.
could you clarify how the x2 value of 7.174 was obtained. Thx
the lambert W function has multiple branches we say. there are 2 real ones and infinetly many complex branches. if you look up how the W function looks like in a graph u can see the 2 real branches bc theres a jump at x=-1/e where the 2nd branch begins leading further downwards :)
Can you write with better pen and bigger
YOu must have mixed this with something else. SAT does not make questions like this whatsoever.
You're doing it all wrong. Look at other youtubers, the most just try to guess a number which could fit the equation and automatically assume that the equation has only 1 solution 🤣
X= 3^4?
How many people need to know this ?
MPRAVISSIMO!!!
W function is very seldomly used in science or engineering. Learning about it is a waste of time for 99.9999 percent of the students.
On the other hand, if you know about it, then the problem is trivial. Nothing interesting in this flick. Besides, lying to attract attention (this is not an SAT problem) is not respectable - even today, even on UA-cam.
😂 You tried
Please talk less ,and continue your calculations
Very slow explanation. It doesn't help to Learners.
Annoying.
Hello,
Like Log, Ln, Sin, Cos, G, g, Pi, etc., e is another decisive and facade number, valid upon Crooks' agreement-the entire ignorant world.
Can this fellow possibly learn to pronounce the word natural the right way ??
And as for this SAT test...what is the point? If somebody wants to study history or political science,he or she does not need to be proficient in math ! Thats nonsense.
Political science is not science
