Explanation:
You know that there are 10 blueberries in each muffin. There are 10 muffins in each box and the total number of boxes is 10.
Then, to calculate the total number of blueberries, you need to multiply the total number of boxes by the number of muffins in each box and multiply this by the number of blueberries in each muffin.
Let be "b" the total number of blueberries. Then:
![b=10*10*10](https://img.qammunity.org/2020/formulas/mathematics/high-school/9fif9065qm9fqpt0jhyunu3mcgb5r31tbh.png)
By the Product of powers property:
![a^m*a^n=a^((m+n))](https://img.qammunity.org/2020/formulas/mathematics/high-school/de31v6cvv3gbm7qbgtuy6d0rjci2lqar0c.png)
Then you can write the expression:
