Homework Statement



lim x^2-x^4
x>Infinity


Homework Equations



i made both of them...e^(2lnx)-e^(4lnx)...then get stuck

im allowed to use limit laws, and no l'hospitals rule

The Attempt at a Solution

Word to the wise. x^2-x^4=x^4*(1/x^2-1).
 


thanks! sorry for the late reply
 

Thread 'Finding the nth roots of a complex number'

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...
