can u separate ln (7+x) into ln7+lnx?

OpenStudy (anonymous):

no ln (7+x) = "the exponent you raise "e" to to get (7+x)"

OpenStudy (anonymous):

can you separate it if it's multiplication or division?

OpenStudy (anonymous):

(7+x) is the argument of the ln, so it's dependent on whatever x is, so now you cannot seperate

OpenStudy (anonymous):

well sort of, "ln7+lnx" would equal "ln7x" but what you have there is not that.

OpenStudy (anonymous):

if you had ln x + ln 7, it could be simplified to ln (7x)

OpenStudy (anonymous):

yeah... what she said. but no, ln(7+x) can't be seperated. what's the whole equation?

OpenStudy (anonymous):

ok then ln7/x can be ln7-lnx? oh i was just wondering what the rule was so i just made that equation up..

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

dont think it can be seperated...it would be a mathematical crime

lol @ eistein+ newton .....
