Needing help with some questions on my College Algebra Clep Study Guide.

I'm not looking for answers. I'm just looking to know how to solve some questions.

Can anyone please help?

So what is your question? ^_^

Multiply both sides by 0.

Multiply both sides by 0.

 

You mean divide, he will get a kickass answer.

Some people just want to watch the world burn...

 

xD

You can post in the Real-Life section. A homework section was already suggested but denied.

Sorry, I don't speak that language.

 

So what is your question?

 

 

 

Have you tried multiplying the top and bottom by the recipricol of the bottom? I am not sure how much knowledge you have, or if you know what that is. Also I am at work so its kind of hard for me to help out because I cant give you a ton of details.

 

Try to multiply the top and bottom by (x-2)/(x-3)

 

 

Doing this will probably give you some like terms, which you can then cancel out on the top and bottom, resulting in one of the answers.

 

This is how you get (a fraction)/(a fraction) into a single fraction.

C looks like a somewhat more complex answer compared to the others, plus C is just the default choice I go for, so I'd go with C.

This helped me out, thanks and good luck in work.

 

I have another set of questions if anyone else can help with:

Oh. Just saw that what he said helped but here is a full working out with explanation.

Question 8.

 

Look at the explanation, otherwise my answers are useless and you won't learn.

 

I didn't bother to multiple the factorials myself on paper but a calculator will verify it.

Arctic's good at this stuff.

This helped me out, thanks and good luck in work.

 

I have another set of questions if anyone else can help with:

 

I am sorry I am at work so its hard to reply to your questions. For number 8 consider this:

 

(n+1)! = n! * (n+1)

now rewrite that expression as

 

((n!) * (n + 1) / n!) - n

 

You can then cancel out the top n! with the bottom n! leaving us with:

n + 1 - n

from there its obvious that the answer is just 1

 

 

 

Ok now that I have time to answer your second question, a variable to a negative power is 1/variable^positive power

 

eg: v^-2 = 1/(v^2)

 

Using that you first add up all exponents, resulting in the condensed expression:

r^(2+2/3) * t^(-1)

 

= r^(8/3) * (1/t)

 

= (r^(8/3)) / t

 

 

If I am unclear or said something stupid I apoligize, I am standing up outside in 100 degree heat on a computer at work l0l

 

It is quite difficult to make proofs in these conditions xD
