+2236 If this were some young student on here, I’d agree that it’s reasonable.
Mr. BB isn’t a young student; he’s an old Blarney Bag who throws BS at questions until some of it sticks. Mr. BB didn’t mistake the symbol for a minus sign; he’s not that blind, and there is a properly used minus sign in the question, so it’s unlikely the asker confused the two symbols.

Here’s a list of squares of concatenated numbers (b_a)
b a concatenated square
0 1 1 1
1 2 12 144
2 3 23 529
3 4 34 1156
4 5 45 2025
5 6 56 3136
6 7 67 4489
7 8 78 6084
8 9 89 7921
45 and 56 have squares where the (a) digit is the final digit of the square, but this is not in the form of (71a).

Mr. BB seems like a phage on this forum, but I suppose in the scheme of things, that Mr. BB’s posts are just weeds, with annoying flies, in the gardens of Camelot. The students will have to learn to recognize them and treat them accordingly.
GETSMART is looking forward to Thanksgiving. The poor turkey is hoping someone will eat him and put him out of his misery.
