Answer :
The answer would be 11i, first you would figure out what the square root of 121 is, which is 11. To simplify, you would write the square root sign and underneath that it would say 11x-1. The negative one is an imaginary number because there really ain't negative square roots of anything. I wish I couldve showed you but I don't have a camera. I hope I expllained it to where you can understand Sorry.
