Question

Determine whether each of the following problems will have a rational or an irrational answer. Your answer should be either the word “rational” or “irrational. 8+3.141592654

Answer 1

3.141592654 is π, π is irrational number, so 8+3.141592654 is irrational

Answer 2

If you meant 8+pi, then the answer will be irrational, because the sum of a rational number and an irrational number will result in another irrational number.

But if you really meant 8+3.141592654, then the answer is actually rational, because although pi is irrational, 3.14159254 is rational, and the sum of two rational numbers is another rational number.
