Solving a triple natural logarithm equation

[@bprpmathbasics]

What if we put them on a right triangle? Here: kzbin.info/www/bejne/eX7He4Otesd4bqM

[@pimpaovieira]

Steve, can you make a cubic equation tutorial?

[@Johnny-tw5pr]

Just factor with horner's method by far the easiest

[@klepikovmd]

@@Johnny-tw5pr does Horner method works for complex roots?

[@Johnny-tw5pr]

@@klepikovmd technically if you can figure them out in your head yes

[@klepikovmd]

@@Johnny-tw5pr it means no 🤣

@@Johnny-tw5pr it does not work for irrational roots .

ln(2x²) = ln(3x) ln(2x²) - ln(3x) = 0 ln(2x/3) = 0 2x/3 = 1 x = 3/2 There's another way to do it. Enjoy!

lnx + lnx +ln2 =lnx +ln3 lnx=ln3-ln2 X=3/2

ln(0) is really an underrated undefined, ngl

[@cyndemercy8409]

Alternatingly, you could also do lnx= ln3x-ln2x which is lnx= ln(3x/2x) or x = 3/2

Hello! I really enjoy your content! Hope you're doing a great day!!

[@yotamambar8047]

Can you make a video with a difficult ln equation? That would be nice.

[@好吧-h6k]

a lot of logarithmic equations you just have to hope they’re solvable

[@husklyman]

ln(2x) =ln x + ln 2 Doing the same with ln 3x we get the equation ln(x)+ln(x)+ln(2)=ln(x)+ln(3)\-ln(x) on both sides ln(x)+ln(2)=ln(3) ln(x)=ln(3)-ln(2) ln(x)=ln(3/2) x=3/2 Another way to solve it

[@davidseed2939]

yes and this way doesn't throw up the spurious x=0 solution

[@hefesan]

You can also entirely skip expanding the logarithms and just do lnx + ln2x = ln3x | -ln2x --> lnx = ln(3x/2x) | e^() (the x just cancels out) --> x = 3/2

3/2, fundamentally multiplying the arguments

Steve, can you make a tutorial teaching how to do integral by parcial fraction?

[@Johnny-tw5pr]

He already has

[@rosalestomlesther1772]

Wrong channel dude... "just algebra"... Go to the main to see fun-mindcracking maths

[@lumina_]

he has like 5 vids on that lol. on main channel

ln x + ln 2x = ln 3x => ln x + ln x + ln 2 = ln 3 + ln x => ln x + ln 2 = ln 3 => ln x = ln 3 - ln 2 => ln x = ln 3/2 => x = 3/2

[@hefesan]

Lnx + ln(2x) = ln(3x) ln(2x^2) = ln(3x) | e^() 2x^2 = 3x | /2 x^2 = (3x)/2 | /x X= 3/2 This is how i solved it

[@pranavamali05]

thnku

[@narsinghmahilang3200]

Nice T sart sir

[@plislegalineu3005]

or... we can just separate the ln's as ln(2*x) = ln(2) + ln(x) and same for ln(3*x) and solve for ln(x) and "e to this power, e to that power"

[@SuleimantheMagnificent9825]

ln(x)+ln(2x)=ln(3x) ln(2x^2)=ln(3x) 2x^2=3x 2x^2-3x=0 2x.x-3.x=0 (2x-3).x=0 x=0 but the x cannot be equal to 0 2x=3 x=3/2 so the only answer is x=3/2

[@johnathaniel11]

I solved the moment I saw it

Can you say me hello???, please just Álgebra????

[@yogi30051972]

Hello

[@DefenderTerrarian]

I got x=3/2 mentally. No paper or calculator.

[@sakkiediereaper]

what if there is an imaginary answer over in the complex world??? 👀👀

[@tornadot1182]

We cancel the ln from all terms and we cancel the x's we get 1+2=3 easy 🤣 (it's a joke)

lnlnlnlnlnlnlnlnlnlnlnlnlnlnlnln Thanks so muc^h

[@dorkmania]

Let Ln(0) = x; taking 'e' on both sides => e^x = 0; there are no values of 'x' that satisfy the equation.
