If y is the smallest positive integer such that 3,150 multipliedby y is the square of an integerthen y must be:A、2 B、5 C、7 D、14
If y is the smallest positive integer such that 3,150 multipliedby y is the square of an integer
then y must be:A、2 B、5 C、7 D、14

If y is the smallest positive integer such that 3,150 multipliedby y is the square of an integerthen y must be:A、2 B、5 C、7 D、14
D、14
3150y=x^2
3150 is the core of the problem so analize it.
3150=(3^2)*(5^2)*2*7
So it is y=14
3150*14=x^2
(2*3*5*7)^2=x^2
and x=(2*3*5*7)
