YAY FOR 3-DAY WEEKENDS!
We jumped right back into exponents today with looking at zero powers. The rule is:
ANY value raised to the zero power will ALWAYS equal ONE (except zero)
Funny that zero is the only exception to the zero exponent rule- hopefully that will make it that much easier to remember!
Here are the notes we took in class- they are pretty short, but they show why anything raised to the zero power is 1: as the exponents increase, we know that means to multiply the base by itself that many times. The greater the exponent, the more times we multiply. The opposite is also true: as the exponents decrease, we determined that tells us that we need to divide by the base. This will be true for any and every value except zero.
For homework tonight, we have a review worksheet. Click here to download today's homework. Tomorrow we will learn about negative exponents... think about how we went from 51 to 50. What did we do? What do you think will happen when we go from 50 to 5-1 ? Then 5-2 ?
