__ z2-n2

8

or simplified 3/4 z2-n2.

is that right? Just want to make sure I'm on the right track. Thanks in advance. : )

Answer 1

~No, you are not on the right track. You should be consulting your math book and/or your teacher, not some dolt like me on Yahoo Answers who is as likely as not going to give you a wrong answer and bum advice just so you will fail because you were too lazy to do your own work or to look to the appropriate resources for guidance.

Answer 2

do no longer positioned parenthesies on your 2d step, extremely of (36b-9) = (18b + 6) make it purely 36b - 9 = 18b + 6. then you definately prefer to get the numbers with the variable (as a result something with a 'b' on it) onto one part and the different selection on the different part... so upload 9 to the impressive part and subtract 18b kind the left part. it may appear as if this - 18b = 15. then you definately prefer to get the variable ("b") by itself, so which you divide the '15' by '18' to take the '18' removed from the 'b' - 18b/18 = 15/18. then your final step is to cut back. you are able to desire to have b = 15/18, so '3' is a numerous of the two 15 and 18, so divide them the two by '3' and you gets - 5/6. and your very final answer would be b = 5/6.

Answer 3

The bottom is almost right. z to the second is in the numerator and the n to the second is in the denominator. The 3/4 part is right.

Answer 4

Answer:

6/8 z^2n^(-2)

Good job...watch those signs!

Answer 5

no
it is not right
the correct answer is
3/4 z^2 n^{-2}

Answer 6

You wouldn't put the - sign where you have it.

-6 z^5n^4
--------------
-8z^3n^6

3/4 z^2 n^(-2)

is one way

3z^2
---------
4n^2

is another.

Answer 7

6/8 z^2n^(-2)

Answer 8

I DONT KNOW SORRY
