lnx-5x=0
find x

Question

lnx-5x=0
find x

anonymous · Answer

is it like  ln(x-5x)=0 or .....

anonymous · Answer

hello tell me to understand

anonymous · Answer

Go to wolframalpha.com and ask the question.

anonymous · Answer

Mom! There's evil in my closet! EVIIIILLL!!!

anonymous · Answer

any way x=$$e^{5x}$$

anonymous · Answer

you have one variable but in two side with exponential so   wolframalpha.com
canot solve it hhhhhhh

anonymous · Answer

the solution is no solution

anonymous · Answer

no...

anonymous · Answer

you cant say  x(1-5) cause the x with ln and -5x is alone so you can't say like 
ln x-5x=0
ln x(1-5) = 0 
ln -4x= 0
-4x = e^0
-4x = 1
x = -1/4

anonymous · Answer

lnx = 5x

anonymous · Answer

so x = e^(5x)
it don't have any solution

anonymous · Answer

when we say x = e^(5x)
so we need x= number that make the two sides be equal
there is no any number to this

anonymous · Answer

until if we derive it be 1=5e^(5x)is critical point 
so .........

tkhunny · Answer

That is not the right equation.  Please think about the Domain.

$f(x) = \ln(x) - 5x$  Domain $x > 0$

$g(x) = e^{5x} - x$  Domain $x \in \mathbb{R}$

Neither has a solution, f(x) = 0 or g(x) = 0.

anonymous · Answer

but how much ln (0) =

tkhunny · Answer

$\ln(0)$ is not a number.
