Question

1. Write z^9/z^3 in simplest form.
a. z^3
b. z^6
c. z^12
d. z^27

2. Which symbol will make the number sentence true? 6/7 ? 0/85
a. =
b. <
c. >

3. Which of the following numbers is an example of an integer?
a. 5 (square rooted)
b. 9 (square rooted)
c. 1/3
d. 0.8

PLEASE HELP ME ASAP!

Answer 1

What do you think the answer is for each of them?

Answer 2

WHen the bases are the same and you are dividing you can subtract the exponents. It is a "fast" way to do the reducing : )

Answer 3

z^9/z^3 = z^(9-3) = z^6
or, consider that
z^9/z^3 = (z^6*z^3)/z^3 = z^6

0/85 = 0
so, ANY positive value is greater than zero, right?

since 9 = 3^2, the square root is 3
I think if you consider the others, you will soon see that they cannot be integers.

Answer 4

1. A
2. C
3. A
maybe these?

Answer 5

ALL wrong!
And I even gave you the final answer to the first one.
Stop guessing and start thinking.
