your logarithms are useless here, just like IRL

x^x=100

ln(x^x)=ln(100)
xln(x)=ln(100)
x=ln(100)/ln(x)

key into a scientific calculator
4
=
ln(100)/ln(ans)
then spam =

to find x

>>680396641
gives 3.59728502354 to 11 decimals

iteration is a bitch

>>680396641
"I just write some distractive bullshit to win some time to bruteforce the result".
x^x is just unpossible.

Newton faggoted just trying to solve it.

>>680397540
that is an iterative formula

that is literally how you get taught to do it

fuck off back to high school, faggot

>>680397540
See: iteration

closed form or gtfo compufags

iterative! such a demanding way to solve problems! are you working on google, right? because that's the way hardcore mathematicians work. iterations... you are so fortrand...

>>680399297
You are positive in retardation. End your life.

>>680399670
>simple problem

kill yourself

>>680399670
>fortrand

the fuck is this meant to say

>>680399670
Go back to failing your degree.
>boo-fucking-hoo

>>680400012
it's 'unpossible' for us to know

>>680400012
4tr& is a coding language you underage b&

>>680400501
no it's not

>>680400501
You mean fortran?

>>680395494

x = sqrt 100

fortrand is the successor of cobold, you dummy

So we have the guy who doesn't know what iteration is, calling things 'unpossible', accusing people of being a programming language which he can't even spell, calling me underageb&. Either this is the worst bait I've ever come across, or the dumbest 8 year old.

Or both.

>>680400982
I seriously hope this was bait too.

>>680400899
you are really wrong, but hey! at least you didn't used iteration! +1 internet

>>680401083
yeah and i burn down a house last week. It's an old language, hence past tense. You autistic fucking five year old

>>680401532
alright, thanks for confirming b8, so long

>>680401747
my pleasure

>>680396641
Retard here, how come spamming ln(100)/ln(ans) works to find x=ln(100)/ln(x) ?
Does it work for x=a/f(x) as well, a:constant, f:function ?

>>680401571

i think you just winrar. still don't know how the fuck mr wolfram solved it, but seems legit

>>680402263
in this case it works because the equation can be arranged to be in that form

take, for example, x^3=e^x

this can be changed to x=(e^x)^1/3, so getting a random value to start with and spamming ans on (e^ans)^1/3 will find it

some of these /b/tards need to go back to high school

x = e^(W(2 (log(2)+log(5))))

>>680402804
no

if f(x) can be rearranged to form x=g(x) then you can use an iterative formula to find x

>>680403206
...by putting x=g(ans) and spamming =

lets say a function has a solution where x=4.5

you could guess 4, put it in an iterative formula, and get 4.9

if you put 4.9 in as the original you might get 4.3

which gives 4.7
which gives 4.38
which gives 4.66

they get closer to the real value the more you iterate
