Question

If x^2/y is an integer, but x/y is NOT an integer, which of the following could be values of x and y?

x=1 y=1

x=3 y=2

x=4 y=2

x=6 y=4

x=9 y=3

Answer 1

Just substitute the values of x and y in the expressions given.


`x=6,y=4 \\ \\ (x^2)/(y) = (6^2)/(4) = (36)/(4) =9 \text{ is an integer} \\ \\ (x)/(y) = (6)/(4) = (3)/(2) =1.5 \text{ is NOT an integer}`
