This week a lot was review for me, but one new thing that i learned was how to work with negative exponents. Before last class I wasn’t sure how, but now I can confidently work with them.

Step 1: when you get the question like the one I have below you want to find the recipricol of it. Every equation has a one underneath it so when you find the repicrol it will be the same equation, but with the one at the top. So basically the 1 and the equation switch, but the exponent turns to a postive

Step 2: solve. I used power to power law and took the 2 exponent outside of the bracket and multiplied it by the exponent attached to the 3 and got 4.

Step 3: I put the 4 as the exponent attached to the 3 and solved it. i got 1 over 81
