First Question:
C. 1
Step-by-step solution:
1. Evaluate 1¹:
1¹=1
2. Evaluate 1-¹⁰⁰⁰ :
Any non-zero number raised to a negative power is 1 divided by that number raised to the positive power. Here, 1-¹⁰⁰⁰ = 1/1¹⁰⁰⁰ = 1
3. Evaluate 1⁰:
Any non-zero number raised to the power 0 equals 1. So, 1⁰ = 1
4. Combine the results:
1¹ + 1-¹⁰⁰⁰ - 1⁰ = 1 + 1 - 1=1
Final Answer: C. 1
