Here are the corrections I need to see:
8.1.1: #2.d.
8.1.3: #27.c: which should he borrow the money from and why?
#35: need the amount of money
8.2.1 (day 2): #42.c and #55 all
8.2.2: #60: need to find the correct simplification
#62: take another look, is 20^11=20^24?
#63: look at this one again and keep in mind what we talked about earlier with parentheses, expand both expressions if that would help to see the difference.
#66. a. try using Giant Ones instead of multiplying all together. Does that make sense?
b. should be 81x^4
c.&d. try again--try writing it out in factored form
#67.b. and #68.b (show your work on both a & b to justify your answers
#70: it's ok to use the hints if you need to :)
#71 is missing
You can do all of these on one paper if you want to/if that would be easier, then upload them all together.
