Plot the following irrational numbers on a number line.

1.2π
2.√311+√17
3.π•√500​

1). Any decimal number that stops is a rational number, and even some
of them that never end are also rational (like 0.33333... is just 1/3.)

2). If 'x' is a perfect square, then the side of the square is the square root
of 'x', and that must be a counting number.  (Integers also include zero,
and it can't be zero, or else 'x' would also be zero.)

3). Sorry, but NONE of those four statements is true.

4). Irrational numbers are not a subset of rational numbers. 
They are a class all by themselves.
