I'm taking a math placement test tomorrow at Citrus Community College in Glendora, CA. I'm pretty good at math, but when it comes to tests, I kind of suck. All I'm taking the test for is so I can fulfill the General Education math requirement for Cal Poly Pomona...So...does anyone know any good math practice websites off the top of their head?

sample problem

(3rad2)*

the asterisk is a "square" or "2nd power"

and the rad is the square root symbol.

 

(3 x Root 2)²


what exactly are you asking for?

 

The answer. I know its kind of simple, but its been 3 years since i took a math class...in which i didnt pass, because i never went

 

Its simple its 18. All you do is square the 3 which gives 9 and then square the square root of 2 which gives 2 and then multiply both.

 

Do you get a calculator? Does it have to be exact or just around the general number?


anyway:

= 3 X Root 2 squared

= 3 X 1.414 squared

= 4.2426²

= 18

 

I knew there was an algebraic way to do it, but calcs are so much easier h:

 

i suck at teh math. T1-83 plus saved my life in high school (i'm one of the geeks who programmed their calculators to cheat on formulas on math tests) :chuckles:

 

so the square cancelled out the rad?

i thought it was 18 also, but wasnt very sure

 

Thats the problem with most kids educated in the American system. No offence to anyone I just think our school system which was under the University of London actually taught you more. Heck I still use a basic scientific calculator and that too only when I desperately need it.

 

oh yeah, placement test says no calculators.
