If N and Y are positive integers and 450Y = N^3, which of the following must be an integer?
I. Y/(3X2^2X5)
II. Y/(3^2X2X5)
III. Y/(3X2X5^2)
None
I only
II only
III only
I, II, III
OA: [spoiler]B[/spoiler
My thought - [spoiler]I thought since y could = 60 then 60/60 = 1. A[/spoiler]
I didn't really know how to set up besides that.
