GMATinsight : not able to understand #1 3,x^2,x^3 has a range of 0 ? i tried substituting value of x as fraction and integer ; not able to solve..

For Set { 3, x^2, x^3 } to have Range = 0, All the values of the set must be same

i.e.  x^2 = x^3 = 3

Which is not possible for any value of x so I am suret here is some mistake in the question

If the set were {1, x^2, x^3} then it's possible for x = 1
