1. The problem is to express the number 1 in a way that is suitable for a 4-mark question, likely requiring detailed explanation or multiple steps. 2. We start by stating the problem clearly: Represent the number 1 and explain it thoroughly. 3. One way to represent 1 is as a fraction where numerator equals denominator: $$1 = \frac{1}{1}$$. 4. Another way is to use the identity property of multiplication: $$1 = 1 \times 1$$. 5. We can also express 1 as a power: $$1 = a^0$$ for any nonzero number $a$, because any number raised to the zero power equals 1. 6. For example, $$1 = 5^0$$ or $$1 = (-3)^0$$. 7. Additionally, 1 can be represented as a sum of zeroes plus one: $$1 = 0 + 1$$. 8. These multiple representations and explanations provide a detailed answer suitable for a 4-mark question. Final answer: $$1 = \frac{1}{1} = 1 \times 1 = a^0$$ for any $a \neq 0$.
