Homework Help: Algebra 2

Posted by Algebra 2 on Wednesday, May 27, 2009 at 2:59pm.

so i got a question and would like to know if i did this right

For problems 1 through 38, transform the given expression to simple radical form. You can check your answer by evaluating it and the original expression by calculator.

on the previous page this definition was given

Simple Radical Form
An expression is in simple radical form if

1. the radicand of an nth root contains no nth powers as factors,
2. the root index is as low as possilbe, and
3. there are no radicals in the denominator

and this is problem number 4

4. 108^(1/3) + 10(32)^(1/3)+ 500^(1/3)

and for my answer I got

about 31.4289(2)^(1/2)

my instructors instructions were to round to four decimals out from the decimal which I have done...

Is this answer correct?
If not what rule did I break?
If I did do this wrong how do I do it the right way?
I checked by calculator and got the right answer so I think I have the right answer and I don't think I broke any of the rules according to my textbook...

so I would just like to make sure...

also what is the point of having the division symbol when 3*1/4 can be written as 3 * 4^-1 which makes more sense to write out like to me because then all of the fraction rules actually work that I was taught back in like 4th grade but was not provided any proof...
