Final answer:
The numbers in ascending order are 1.5, √4 (which is 2), 2π (which is approximately 6.28), and 23.
Step-by-step explanation:
To list the numbers from least to greatest, we first need to know the values of each number. We have the numbers 23, √4, 2π, and 1.5. The square root of 4 (√4) is 2, and since π (pi) is approximately 3.14, then 2π is approximately 6.28. Now we can arrange all the values in ascending order:
- 1.5
- √4 (which is 2)
- 2π (which is approximately 6.28)
- 23
Therefore, the numbers listed from least to greatest are 1.5, 2, 2π, and 23.
