Thank you for the opportunity to help you with your question! Hope your day is going well!

The goal is to to see what multiples of 63 has perfect squares in them

63 is not a perfect square

1 x 63 (still equal 63 is not a perfect square)

3 x 21 (there is not a perfect square)

7 x 9 (ahhhh ha! a perfect square is involved...since 3 x 3=9)

Then

Therefore, this is the simplified expression.
