Question

natural number cannot be a fraction, decimal, or square root?

Answer 1

ture

Answer 2

\[\sqrt{25}\] ;)

Answer 3

resulting in -5 as well zarkon meaning its not natural

Answer 4

lol @ outcast

Answer 5

um..no

Answer 6

\[\sqrt{25}=5\]

Answer 7

+/- 5

Answer 8

no it is not...the notation \[\sqrt{}\]

uses only the principal value

Answer 9

what?

Answer 10

look it up if you don't know it

Answer 11

sorry then sir i bow to ur wisdom

Answer 12

can u link me?

Answer 13

even at that, what you are saying is that all sqrt are natural numbers

Answer 14

sqrt of 235928395819481342 is not going to be a natural number when you take the root

Answer 15

but there's a negative value possible too i dont get principle stuff

Answer 16

it is a notation thing....if you just ask for the square root of a number then it is true that is it +-

if you ask for \[\sqrt{a}\] then the answer is just the principal value (the positive real number...provided a>0)

so for this problem square roots are bad (that is why I put the smiley face)

Answer 17

SO, basically, You can hv a square root of something and it could also be negative AND positive, right? so the square root of somethuing is (therefore) NOT natural???

Answer 18

i thought only imaginary numbers were given the principle value

Answer 19

that is true if you use words to ask for the square root

Answer 20

DUDE. I M SOOOOOOO LOST!!!

Answer 21

square root of 25 is \[\pm5\]

\[\sqrt{25}=5\]
\[(25)^{1/2}=5\]

Answer 22

i still dont get it

Answer 23

http://en.wikipedia.org/wiki/Square_root

Answer 24

There are two square roots of 25. One is 5, one is -5.

The notations \(\sqrt{a}\) refers to the positive square root if you want the negative one you would write \(-\sqrt{a}\). If you wanted both you'd write \(\pm \sqrt{a}\)

Answer 25

Every non-negative real number x has a unique non-negative square root

Answer 26

even by definition it does not include natural numbers

Answer 27

Uh.. Natural numbers are a subset of the Reals.

Answer 28

\[\frac{5}{1}\]...fraction ;)

Answer 29

yes i get what u mean but its not true for all

Answer 30

I meant...1/5

Answer 31

then no

Answer 32

i get what u mean zarkon

Answer 33

it says cannot be a fraction...well it can \[\frac{n}{1}\]

;)

Answer 34

I dont

Answer 35

lol sorry it took me this long to understand

Answer 36

well its the same as saying 1 can be written as 1.0

Answer 37

or 1/1

Answer 38

The statement says a natural number cannot be a fraction or a square root or a decimal. But we've given examples of natural numbers that are. Therefore the statement is false.

Answer 39

if u are in a lower grade i think it would be safe to just say yes

Answer 40

I dont' exactly know for sure, but... to sum it up... I would say that \[\sqrt{x}\] would be the one that comes out positive, and \[-\sqrt{x}\] right???

Answer 41

what class/level is this?

Answer 42

and ther are loopholes to every statement?
Oh, and Its Pre AP algebra 2 that Im taking in eighth grade(ya,I'm so cool) lol

Answer 43
