I apologize for missing posts due to the astronomy camping trip.
Here is a math reflection: In math we learned about imaginary numbers. One important one is i, the sqrt of -1. You can express negative sqrts using i and it's exponents. A list of i's exponents i^1= i i^2=-1 i^3=-i i^4=-1 i^5=i and so on, so on... If you want to express a number like the sqrt of negative -9 using i, you can rewrite it as the sqrt of nine times the sqrt of negative one, or 3i. This rule is represented as the sqrt of a times the sqrt of b is the sqrt of a times b. This works for division as well. There is a worksheet about this week worked on in class, it is due next week, and is on Google Classroom.
