Need help solving this problems:

For the given polynomial function, find the requested value?

1.
(c+8/3)with an exponent of 2 on the outside of the parenthesis

(c + 8 divided by 3)exponent 2

2.
a) Identify the Degree, b) arrange in descending-exponent form

-20a, a has an exponent of 8
(negative 20a with an exponent of 8)

Hi magosalim;

For 1)

For 2) Please give that a try on your own. This one you should know.

For 3)

If I tell you:

Can you now complete the problem? Please give it a try. Post what you get.

Re: Need help solving this problems:

Hi bobbym,

Thank you so much for the answer of the first problem.  I have to figure out how you got the answer.  I did the old fashion way of getting the answer by doing the smiley face system. The answer came out the same with your answer!
The 2nd problem, I am having trouble with...
Since the problem is not in open -20a and close parenthesis with an exponent of 8, why would you put the -20a inside the parenthesis with the exponent of 8?  Should the 8 only have power over the a? and not the whole thing?    I know the Degree is: 8
How do I arrange it in descending-exponent form since you only have one term?

Re: Need help solving this problems:

Hi;

I would assume that they want you to put the answer to 1) in descending exponent form.

-20a, a has an exponent of 8

You are correct the question is badly worded. But I think they want the parentheses around the -20a, like this (-20a)^8. To be on the safe side why not do it both ways?
