To "write 81 as a product of 3's" means expressing the number 81 as a multiplication of the number 3. In other words, you need to find a series of multiplications using the number 3 that will result in the number 81.
Let's break it down step by step:
1. Begin by dividing 81 by 3: 81 ÷ 3 = 27. This means we can write 81 as 3 multiplied by 27.
2. Next, divide 27 by 3: 27 ÷ 3 = 9. Now we can write 27 as 3 multiplied by 9.
3. Again, divide 9 by 3: 9 ÷ 3 = 3. Now we can write 9 as 3 multiplied by 3.
Putting it all together, we have 81 = 3 × 27 = 3 × 3 × 9 = 3 × 3 × 3, which shows 81 written as a product of 3's.
