🧮 algebra

1. The problem asks whether any number raised to the power of 1 is equal to the number itself. 2. The rule for exponents states that for any number $a$, $a^1 = a$.

1. The problem states: "Any number raised to 0 is equal to 1." We want to understand why this is true. 2. The rule for exponents is: $$a^m \times a^n = a^{m+n}$$ where $a$ is any n
