Write the expression as a single log

posted by .

Write the expression as a single log. Express powers as factors
ln(x/x-5) + ln(x+5/x) - ln(x^2-25)

  • Write the expression as a single log -

    I am sure you meant to type

    ln( x/(x-5) ) + ln( (x+5)/x ) - ln(x^2 - 25)
    = lnx - ln(x-5) + ln(x+5) - lnx - (ln(x+5) + ln(x-5)
    = -ln(x-5) + ln(x+5) - ln(x+5) - ln(x-5)
    = -2ln(x-5)
