Explanation:
Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.
=
![-1 * (3)/(7) * (3)/(7) * (3)/(7)](https://img.qammunity.org/2022/formulas/mathematics/high-school/ocyb28bkzfovtwilucwius6e876bemi3vo.png)
We then multiply by -1 to (3/7)^3 to get the exact answer.
