Use your rules of logs
ln(x^4)-ln(x^2)=2
ln (x^4/x^2) = 2
ln(x^2) = 2
2 lnx = 2
lnx = 1
e^1 = x
x = e
or
ln(x^4)-ln(x^2)=2
4lnx - 2lnx = 2
2lnx = 2
lnx = 1
x = e^1 = e
ln(x^4)-ln(x^2)=2
ln (x^4/x^2) = 2
ln(x^2) = 2
2 lnx = 2
lnx = 1
e^1 = x
x = e
or
ln(x^4)-ln(x^2)=2
4lnx - 2lnx = 2
2lnx = 2
lnx = 1
x = e^1 = e
thanks alot man, wow it makes alot of sense.
