This week in math 10, our class learned exponent laws (multiplication, division, power). It was mostly review to refresh what we learned in grade 9 math, but I also learned how to convert negative exponents into positive exponents, which was new to me.
In order to solve a problem with a negative exponent, you would have to first locate the negative, and if it is located in the numerator bring it down to the denominator and vise versa. In other words, flip the negative reciprocal into a positive. 🙂
