,-7 pi, 7, -19.__38__, ^3√175, order these from least to greatest

Answer 1

To order the numbers from least to greatest, we need to approximate their values:

1. -7π

   • Approximately -21.99 (since π ≈ 3.14, -7 * 3.14 ≈ -21.99)

2. 7

   • Exactly 7.

3. -19

   • Exactly -19.

4. 0.38

   • Exactly 0.38.

5. ³√175

   • We can estimate the cube root of 175.
   • Since \( 5^3 = 125 \) and \( 6^3 = 216 \), \( 5 < ³√175 < 6 \).
   • Approximating further, \( ³√175 \) is around 5.57 (using a calculator, it's approximately 5.57).

Now we can list the approximated values:

• -7π ≈ -21.99
• -19
• 0.38
• ³√175 ≈ 5.57
• 7

Now putting them in order from least to greatest:

1. -7π
2. -19
3. 0.38
4. ³√175
5. 7

Thus, the ordered list from least to greatest is: -7π, -19, 0.38, ³√175, 7.
