Hello Melody!!!!,
I am going to be VERY honest about this....the answer I actually got, was exactly the same as what you got...I promise you that. this morning when I posted the problem, i did not have my paper that i worked on, with me, so I did the sum afresh...and got lost. I figured that it was'nt a train smash if i did not put the sum exactly as I actually had it....the answer is wrong any case...so I left it as such
Yes I also did the 3 "i"'s etc...
Melody, yes, I checked and re-checked that answer....the "i" looks like it is within the square root sign...maybe they did a mis-print?
