In my history book the expression square root (with a 3 in the nook( around a square root of ten is given. It says it equals the square root of ten with 6 in the nook. However, I don't understand where the six came from. I thought you multiply the two things in the nooks together. So 3 and 1 (since nothing was written in the nook of ten) would equal three. I thought it would be the radical of ten with a three in the nook. How did I go wrong?

square root has a understood 2 in the nook, it is to the square root. 3 x 2 is six.
