Find the derivative of y with respect to x.
y= [(x^5)/5]lnx-[(x^5)/25]

How would I go about doing this?
Should I use the product rule to separate
(x^5)/5]lnx ?

  • Calculus - ,

    I would change the variable, let u= x^5/5

    then

    y= u ln x-u
    y'=u/x + u' lnx -u'

    and surely you can find u'
