ACCUPLACER College-Level Test Help...

**BeSweeet** · May 23rd 2009, 11:57 AM

I'll be taking the math portion of the ACCUPLACER test on Tuesday. There are three portions of the math test: basic arithmetic, elementary algebra, and college-level math.

For the first two portions, I can ace those easily. But when I get to the college-level math, it's extremely confusing to me.

Here is a PDF (that contains sample questions for the test) that I've been working on: http://professionals.collegeboard.co...r-students.pdf

Questions 1-10 of the "College-Level Mathematics Test" portion is the area that gets me.

For problem 1, I figured I could just subtract the exponents, which would result in 2/2, which then results in 1, so there is virtually no exponents. So, the problem would look like 2-2, which would equal 0, but that isn't a choice. I'm pretty sure I'm doing something wrong somewhere...

For problems 2-5, I just have no idea of what to do.

For problem 6, I feel as if there isn't enough information in the problem to figure out the answer. It wants to know how many two-bedroom apartments there were. I don't see how someone could find that out...

For problems 7-10, I just have no idea of what to do.

I kinda feel like a retard... I learned this stuff in Advanced Math and I already forgot it

you are missing a lot of basic algebra knowledge ... your thinking on #1 shows you need to relearn those basic algebra skills that you forgot.

$2^{\frac{5}{2}} - 2^{\frac{3}{2}} = 2^{\frac{3}{2}}$

if you don't know why, then let the ACCUPLACER test do its job ... to accurately place you in the correct starting course.

I don't wanna have to take a math class where I get no credits for.

Is there a website where I can quickly refresh myself of this stuff?

Virtual Math Lab - College Algebra

good luck.

$2^{\frac{5}{2}} - 2^{\frac{3}{2}} = 2^{\frac{3}{2}} =\sqrt{2^4}\sqrt{2}-\sqrt{2^2}\sqrt{2}=4\sqrt{2}-2\sqrt{2}=2^1*2^{\frac{1}{2}}=2^{\frac{3}{2}} $

$2^{\frac{5}{2}} - 2^{\frac{3}{2}}$

factor ...

$2^{\frac{3}{2}}(2 - 1) = 2^{\frac{3}{2}} \cdot 1 = 2^{\frac{3}{2}}$

That is something I can't remember ever learning.

I think I'll do fine on the test. I've doing several different practice ACCUPLACER math tests and I did good on all of them (I got about 10/20 right on the college-level math part).
