Oh my gosh, ROFL..
I really love that.
You call me David haha. I'm a girl, David Archuleta is my fav singer.
Anyway, the question ask you the smallest number that if you multiple that number with 3150, the result is is the square of an integer.
3150= 5^2. 3^2. 14=15^2 . 14
So you must multiple 14 to get:
14. y = 15^2 . 14^2=(15.14)^2

In this side of the ocean we (act, I) have got no clue about David Archuleta! Sings well though.
Thanks for explaining the q.
