    Hello,

    For the first one, can't you write this : \frac{2x+7}{x}=2+\frac 7x ? Is this what you mean in "not supposed to divide" ?

    Ohey you're right. That's simple enough...you do divide, but it turns into a question with log e x as the answer because you end up with 7/x, and the x has no power.
    Thanks very much...for your quick and simple answer

    Hi
    for the second problem
    integration of (x^2+x^4/x)dx
    =integration of (x^2/x+x^4/x)dx
    =integration of (x+x^3)dx
    =(x^2)/2+(x^4)/4 is the answer
    here i'm considering instead of integration symbol as integration, i hope this steps are easy to calculuate.

    step: first i divided by x
    step: then integration with respect to x by using the formula of
    integration of x^n dx= (x^n+1)/n+1
