The square of a certain whole number N is N squared.If 60 is a factor of N squared ,its possible that xis not a factor of N squared.

Answer 1

true, depending on the value of x.

Answer 2

A.16
B.25
C.36
D.100
These are the choices for the question

Answer 3

60 divides N^2
60 = 2^2*3*5

That means that 3^2 and 5^2 must also divide N^2

So, only 16 might not be a factor of N^2

(2*3*5)^2 = 900

16 is not a factor of 900; then others are.
