Perform each calculation and observe the answers \[ 3.1^{0} \pi^{0} \quad 48^{0} 140^{\circ} \]

Let's perform each calculation step by step. 1. **Calculating \(3.1^{0}\)**: Any non-zero number raised to the power of 0 is equal to 1. Therefore: \[ 3.1^{0} = 1 \] 2. **Calculating \(\pi^{0}\)**: Similarly, \(\pi\) (which is approximately 3.14159) is also a non-zero number. Thus: \[ \pi^{0} = 1 \] 3. **Calculating \(48^{0}\)**: Again, since 48 is a non-zero number: \[ 48^{0} = 1 \] 4. **Calculating \(140^{\circ}\)**: The notation \(140^{\circ}\) refers to an angle measurement and does not involve exponentiation. Therefore, it remains as: \[ 140^{\circ} = 140^{\circ} \] Now, summarizing the results: - \(3.1^{0} = 1\) - \(\pi^{0} = 1\) - \(48^{0} = 1\) - \(140^{\circ} = 140^{\circ}\) The first three calculations yield the same result of 1, while the last is an angle measurement.
