    Help Simplifying!

    I need help with this. The problem needs to be simplified and I'm confused:

    ln [(e^5x)/x(x^4+1)]

    Thanks!

    Well Bandnerd...I am going to assume that this is yoru problem \ln\bigg[\frac{e^{5x}}{x(x^4+1)}\bigg]...if so then we begin with this ln(e^{5x})-ln(x(x^4+1)) due to the fact that the quotient of a log is the difference of the individual logs...next we have 5x-[ln(x)+ln(x^4+1)] this was done using the fact that \ln(u(x)) and e^{u(x)} are inverses and using the fact that the products on the interior of a log can be split into the addition of the logs....next we just have to distribute the - to get ln\bigg[\frac{e^{5x}}{x(x^4+1)}\bigg]=5x-ln(x)-ln(x^4+1)
