b.7^6
c.7^12
d.1^6
2. Simplify the expression z^8/z^12
a.z^20
b.z^4
c.1/z^-4
d.1/z^4
3. Simplify the expression (-3^4)/(-3^4
a.(-3)^1
b.0
c.1

4.Which expressions can be rewritten as 1 over the base raised to a positive exponent? 2
a.b^-2/b^4
b.w^5/w^-3
c.5^3/5^5
d.4^7/4^7

1.B

2.D
3.C
4.A and C
100%

steve is right i got a 100%

1. B
2. D
3. C
4. A and C

The quiz answers were wrong from the connexus person I wound up getting 2/8.

The correct answers are
1. X^7
2. H^9
3. 1/16
4. 1
5. =
6. -16r^2-10
7. 2a^3+8a^2
8. 9y^2-6y
Did AIP and got a new score of 8/8

^^ THANK YOU SO MUCH MARTHA I GOT 100%

Thank you for the answers but what happened to all the other answers for any other assignments it's like they all just disappeared I've had several quizzes I've needed answer for ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ

100% thank you Steve

Yanni is 100% right, with Connections i got 2/8 :(

Martha is right 5/5 100%

yes steve is correct, i just got 100 from steve's answers.

#1. 7^(9-3) = 7^6

NOT 7^(9/3) = 7^3
subtract exponents when dividing numbers. What you have is

7*7*7*7*7*7*7*7*7
------------------------
ย ย ย ย ย ย 7*7*7

only three of the 7's cancel

#2
z^8/z^12 = 1/z^4 = z^-4
So, D, not C

#3 ok

#4 not sure what that trailing 2 means, but
a.b^-2/b^4 = (1/b^2)/b^4 = 1/b^6
b.w^5/w^-3 = w^5 * w^3 = w^8
c.5^3/5^5 = 1/5^2
d.4^7/4^7 = 4^0 = 1
Looks like A and C both work.
