Write down all elements of the set {xer: x3 -x = 0).

The elements of given set are -1, 0 and 1.

Step-by-step explanation:

The given set is

We need to find all the elements of given set.

The given equation is

          .... (1)

Solve this equation o find the value of x.

Taking out common factors.

Using zero product property,

All rational and irrational numbers are real numbers.

On solving equation (1) we get x = -1, 0, 1. All these numbers are real number. So, the elements of given set are -1, 0 and 1. The set is defined as

{ -1, 0, 1}

Therefore, the elements of given set are -1, 0 and 1.

8121 because

130,000 divided by 16 is 8121
