stop moving things around as if that makes progress. 3m=m^3 Clearly a common factor of m, so either m=0 or divide by m 3=m^2 square root m =±√3 how can you take 10 minutes. These are exam questions with a limited time

i√3 and -i√3 are not solutions. Substituting into 3m = m^3 : 3i√3 ≠ -3i√3 -3i√3 ≠ 3i√3 Plus, the cubic can only have up to three roots, which are 0, √3 and -√3

m1=0 => 3 = m² => m2,3 = +/-SQRT(3)
Doesn't get much more basic than that.
Just need to note that dividing both sides by m requires m≠0
m³-3m=0
m(m²-3)=0
●m=0
●m=±√3
I did it in my brain 😂
Same 😂
Yep. Only saw the video because I thought it was a trick question.
@yottaforce yes bro...
This is too easy 😂
and i😂
The quadratic equation also works.
You can also quickly solve for the positive root by taking the log of both sides and solving the resulting equation of log m = (log 3)/2.
@@jasonstorm-wm2vd Having my father drill into me the use of various slide rules, this is how I naturally think on these questions.
m^3=3m
Or m^3-3m=0
Or m(m^2-√3^2) =0
Or m(m+√3) (m-√3) =0
Or m=0, m=-√3, m=√3
this is super easy actually

3=m^2

nice solution , simple and clear
3m=m^3
3m=mm^2
3=m^2
ثم حل المعادلة حيث mيعادل جذر ثلاثة او ناقص جذر ثلاثة
It’a the same thing as the video, just you need to precise that m is not equal to 0, else you wouldn’t be able to divide by m to get 3=m^2
3 = 3 vera
3m = m^3
^3√3m = ^3√m^3
m+m+m=m•m•m
3•(3+3+3)=3•3•3
3•9=27
27=27 vera
^3√27=3^√27
3=3 vera
3m = m^3 / 3m= 3•(3+3+3)
/ m^3 = 3^3 / m=3
Nice explanation.
That square root party hurt my brain. M=0 took me 3 seconds, how can it also equal something else? It can only be one value
3m = m³
3 = m²
m = ±√3
Exactly, I didn't know how he actually had to do that factoring lmao
You forgot m=0
i literally solved it in my head. Idk what the target audience is but for a 12th grader german student this was way to easy.
Yes bro I am also a 12th grader student but not German and it actually took me 30 sec....
3m=m^3
Or m^2=3
Or m=√3
m^3 (m ➖ 3m+3).

It has 3 solutions
@kriz5652 i know but my mind just says 0 cuz i am not good at maths
not flexing but i solved this question within a glance ...because u(sir) solved same question few videos ago...

Where is 0 and -sqrt(3) ??
It's okay
Easy one, maybe too easy
this is too easy😂😂
A little bit over-thought.
Lower mathematics...
I call shenanigans, you never taught math! Proof --> Your handwriting is legible.
Click bait
Way too complicated, you were almost at the answer in step 2.
This is a waste of time. 15 second was enou to,solve it
De cabeça pude encontrar as soluções:
m = 0
m = √3
m = i √3
m= - i √3
i√3 and -i√3 are not solutions.
Substituting into 3m = m^3 :
3i√3 ≠ -3i√3
-3i√3 ≠ 3i√3
Plus, the cubic can only have up to three roots, which are 0, √3 and -√3
@jdbtwo perdoe-me. Fiz as contas mentalmente. Você está correto.
