Question 653436
<font face="Times New Roman" size="+2">


Depends.  Are you allowed to use your calculator?  If not, do you know enough Calculus to take a first derivative?  Or did you want the long hand process for taking cube roots?  I can get you a link to the process, but it is as ugly as a mud fence.  Best, especially with a relatively small radicand like 320, is to just guess and check until you get it as precise as you like.  Still it is a long and laborious process with little value to anyone, particularly in this age of computers.

My calculator said it, I believe it, that settles it
