Final answer:
The partial products for 72x4 are 280 and 8, which result from multiplying 70 by 4 and 2 by 4, respectively.
Step-by-step explanation:
In the multiplication of 72 by 4, we can break down 72 into 70 and 2 to find the partial products. To calculate the partial products:
- Multiply 70 by 4, which gives us 280.
- Multiply 2 by 4, which gives us 8.
Therefore, the partial products of 72 x 4 are 280 and 8. To get the final answer, we add the partial products together: 280 + 8 = 288.
