Does xk1 mean k1 times x?

What course is this for? I can think of a number of ways to do this (it is what is called a "linear first order differential equation with variable coefficients") but which would be appropriate for you depends upon what techniques you know.
 
Hi,

xk1 means k1 times x.

I guess i need the easiest techniques.
 
Write it in the form,
y'+p(x)y=q(x)
And use the integrating factor method.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
