Question

How would you solve \[4ln(x) - 3 ln(2x)= 10\]?

Answer 1

PLZ SOLVE THS QUESTION

Answer 2

\[\ln x=10+3\ln 2 \]

\[x=8e^{10}\]

Answer 3

ln(x^4)-ln(8*x^3)=10
ln(x/8)=10
x/8=e^10
x=8*e^10

Answer 4

Is the equation editor broken?
4ln(x) - 3 ln(2x) = 10
ln(x^4) - ln((2x)^3) = 10
ln((x^4)/(8x^3)) = 10
ln(x/8) = 10
x/8 = e^10
x = 8e^10

Answer 5

Oh that makes sense...I feel dumb :P Thanks

Answer 6

i mentally solved it ...u see thing is :
3ln(2x)=3{ln(2)+ln(x)}
now wen this is subtracted from 4ln(x)
we get ln(x)-3*ln(2)=10
shifting 3*ln(2) on rhs....
\[x=e^{10}\]
