Whenever we have a negative exponent, that means that the function should be in the denomenator. then the exponent will be positive.
Example
16^-4 = 1/(16^4)
The first one YES and the last one NO!
To determine when Mya will have both lessons again on the same day, you will list the multiples of each number of days because to show every 4 or 6 days, you will count by 4's and 6's.
When you get to the first number that is the same, that will be the next time she will have both lessons again. This is called the least common multiple (LCM).
4, 8, 12, 16, 20, ...
6, 12, 18, 24
In 12 days she will have both lessons again.
