7th Period Test 1
Everyone from 7rd period, this is where you need to comment with your solutions to the problems.

pg. 131 #44
a^4B^2 ab^5
= ab(a^3b + ab^4)
Page 132 #27
8r^(1/2)s^(-3) /
2r^(-2)s^(4) =
4r^(1/2)r^(2) /
s^(3)s^(5) =
4r^(5/2) / s^(7)
*(1/2)+(2/1)= (1/2)+(4/2)=
(5/2) is how you get the ending
answer.
pg. 131 #20
(a^2)^(-3)(a^3b)^2(b^3)^4
a^(-6)a^6b^2b^12
a^6b^2b^12/a^6
=b^14
Courtney, if we pull another b out, we'll get ab^2*(a^3 + b^3) and (a^3 + b^3) can factor too.
Summer, remember we don't want to leave any fractional exponents in our answer.
