 Question 75144: I have to do a project on radicals and square roots. Part of our extremely confusing assignment is to show our radical "disguised" as an imaginary number, both simplified and unsimplified. I have looked up imaginary numbers and though I understand the definition (sort of) I don't understand at ALL how this translates to my radical. My radical is [the square root of] 6875.

 Question 75897: Ok so this is an algebra 2 question, but i couldnt find anything about roots in the algebra 2 section so i figured i would ask it here. I am not exactly sure how to type a square root on a computer so substiture the divisiont mark (/) as a square root symbol, but here goes: /-6 x /-15 when i asked my teacher she told me to start out by changing it to: i/6 x i/15 but i am stumped after this part. Sorry if my question is somewhat confusing because i cant type a square root but thx for this wonderful site and all your help i would probably be failing if it wasnt for you guys.
