Answer 1

I can help you...this is quite simple once you get the hang of it, ok?

Answer 2

ok thanks!

Answer 3

Wait, you have a, b, and c in the numerator and x, y, and z in the denominator. Nothing there simplfies at all.

Answer 4

oh sorry it says rewrite the expression

Answer 5

You can only cancel between variables when the variables are the same. If you had a, b, c on top and bottom, then you could cancel.

Answer 6

it can't have a denominator

Answer 7

What do you mean by rewrite it?

Answer 8

so there is no denominnator or fraction line if you will

Answer 9

There is no way you can simply eliminate the denominator when there is no other "side" to this. If this was one expression = to another, then you could possibly do something about cross multiplying or something. Not to belittle you so please don't take this wrong, but are you sure you copied the problem correctly? And that the instructions are correct as well?

Answer 10

Complete this item. (Enter letter variables in alphabetical order.)

Rewrite the expression so that it has no denominator. (Note: do not use a fraction line in your answer. Also, use '' for multiplication between numbers. )

Answer 12

By any chance are you working with exponents and their negatives and the like?

Answer 13

yeah ^ is an exponent sign

Answer 14

Are you learning how to eliminate negative exponents and then how to write an expression using negative exponents? I'm trying to get at whether or not you are using negative exponents. "negative" being the important word.

Answer 15

Rewriting that with no denominator will cause us to have to use negative exponents.

Answer 16

yeah negative exponents

Answer 17

Very good! Ok then...

Answer 18

thanks!

Answer 19

When you move a number or a variable to the top from the bottom, you have to include a negative exponent with it. Like moving the 8 from the denominator to the numerator moves up as\[8^{-1}\] \[8^{-1}=\frac{ 1 }{ 8 }\]

Answer 20

By the same method, \[x ^{4}\]moves up to the numerator as \[x ^{-4}\]because\[x ^{-4}=\frac{ 1 }{ x ^{4} }\]

Answer 21

Are you getting the pattern here? You want to try the y^3?

Answer 22

umm

Answer 23

so it is 1/3z?

Answer 24

for 3 it equals 1/3

Answer 25

IM stuck?

Answer 26

Ok, let me start you off here...

Answer 27

Like this...I will do the first two terms from the denominator so you can see. Okk?

Answer 28

\[3a ^{2}b ^{3}c ^{5}8^{-1}x ^{-4}...\]Do you see how you will bring up the y^3 and the z^1?

Answer 29

yeah

Answer 30

so 3^-1

Answer 31

y^-3 x

Answer 32

It would be y^-3, no x.

Answer 33

what about the x then -x?

Answer 34

Now you have\[3a ^{2}b ^{3}c ^{5}8^{-1}x ^{-4}y ^{-3}...\]The x is to the negative 4. See it there after the 8^-1?

Answer 35

What about the z?

Answer 36

\[z=z ^{1}\]

Answer 37

yeah thats what im meant the z not the x.

thanks!

Answer 38

What happens to the exponent of 1 when you bring it to the top?

Answer 39

it turns negative?

Answer 40

\[3a ^{2}b ^{3}c ^{5}8^{-1}x ^{-4}y ^{-3}z ^{-1}\]

Answer 41

wow great!

Answer 42

Yep! It does turn negative! Very good! Do you get it now?

Answer 43

yeah! thanks so much!

Answer 44

I appreciate the help!

Answer 45

You're so very welcome!!! (I'm a teacher...I love to help!) ; )

Answer 46

well your great at ti!
