Square roots

fairyprincess2003 · Apr 5, 2002

HI there

all you do is take whatever squared ='s that number. For example the square root of 16 is 4, because 4 times 4=16, or 4squared=16.

Another example is the square root of 4 =2, bc 2 times 2=4. or the square root of 64 is 8, why, because 8 squared is 64.

I hope this helped. Good luck:)

You are kidding right lol I thought that there was a ton more involved than that.

what about uneven #'s.

thanks

Well, 4 and 64 are fairly easy numbers to figure the square root of. But it could take you quite awhile to sit around multiplying numbers until you come up with the square root of 676.

I believe there is an actual formula for figuring out the more difficult numbers, but what exactly it is, I do not know. I just have brief, painful memories of it from math class sooooo long ago

Hopefully Mario will see this question. I believe he's the resident mathmetician

HI

If you got to http://www.math.com you'll find a lot of information about square roots and other math formula.

God bless!

Thanks for the website about math. I'm taking my entrance exam next month and I need to refresh myself with algebra!!!...yikes:eek:

Hi Fatima,

I'm taking my entrance exam on April 27 and that's why I know about the math website. And I'm also from NJ.

Nursing math is most concerned with ratio and proportion. Be sure to become familiar with these. Good luck!

Hey there again:)

Actually you could say I'm pretty good with math, was a psych stats TA, have taken AP math in high school, finished college physics and algebra and currently on calc.

The point, thus far I know of no "special" formula to get a squared root, plain and simple you have to figure it out, for most classes that require it from an odd number, or a non perfect square, you can use a calculator. It would be wise for you to memorize the perfect square roots, and just know where they are coming from in the case that you do have to sit there and figure it out. Just remeber the only technique I have ever known in that it is the number that when multiplied by itself = that number. Unless somewhere down the line you get a problem like let's say the square root of 27. Well we know that 9*3=27, and square root of 9 is 3, so we could say our answer as 3 square roots of 3. I hope you are not confused.

But like a previous poster said don't worry to much about square roots, I have yet to use them in clinicals. Good luck sweetie:)

noeljan222, thanks for the advise. I have to take a entrance test for the school next week & it is a killer. I have to pass with pretty good grades in order to get into the nursing program. I have to learn basic Algebra before then. I guess I just have to buckle down & study, study study..... Thanks for the help

By the way I lived not to far from Bufflao last year. It is a nice place

You are welcome Lisa:)

Just try to review the basics, it will come to you.

I am from Buffalo, and I go to school in Buffalo. It would be nice to take a vacation soon, it's actually snowing at this moment:(

Well let us know how you do. Good luck, and if you have any more questions let us know.

The basics are what is in order for a entrance exam. Make sure you remember how to do the basic multiplication,dividision, addition and subtraction of fractions, basic algebra/finding X, and know how to set up and solve ratio and proportion problems. You should be fine with just that. Anything else they will prompt you on in nursing class.

You will do fine.
