What square numbers make 45?

Answer 1

There are many options:

1 + 1 + 1 ... (45 times)

1 + 1 + 1 ... (9 times) + 4 + 4 + 4 ... (9 times)

4 + 4 + 4 + 4 + 4 + 25

1 + 1 + 1 + 1 + 4 + 4 + 4 + 4 + 25

1 + 1 + 9 + 9 + 25

4 + 16 + 25

1 + 1 + 1 + 1 + 16 + 25

and what you were probably looking for but did not specifically ask for, 9 + 36
