One plus two = 6
Three plus four = 9
Five plus six = 7

There are a few number combinations where (AB+CD)² = ABCD
where A, B, C and D are all single digits.
The digits may or may not be the same.
For example, the first one is (00 + 01)² = 0001
I've found three others so far. Can you find them, maybe more?
