Homework Statement


How fast is the area of a square increasing when the side is 3 meters in length and growing at a rate of 0.8meter/minute?


Homework Equations


SA=LW
L=3
dL/dt=0.8

The Attempt at a Solution



I have no clue how to start this and I'm bad at word problems.

Eh, I can somewhat agree ... but I still assume OP didn't realize W=L :p (noticing in the post, L=3)
 

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...
