Hello,
The value of root -i has no significance and if you find it in answers, you can leave it without further simplification.
But it can be simplified as mentioned below:
Root -i can be written as: root -1 * root i
root -1 is i again.
So, the total expression is : i * root i.
Adding the powers, we get: root -i = i ^ (3/2).
Hope this helps.
Thanks.
