## anonymous 5 years ago wilL someone pLease heLp me . . . Identify the classifications that apply to the real number. √12 a.)natural number, whole number, integer, rational number, terminating decimal b.)irrational c.)natural number, whole number, integer, rational number d.)rational number, terminating decimal

The real number in question is sqrt(12)?

2. anonymous

sqrt(12) = sqrt(3*4) = 2sqrt(3)

3. anonymous

sqrt(3) is irrational.

4. anonymous

and we know that the product of a rational and irrational (nonzero) is always irrational.

5. anonymous

idont understand . . .

6. anonymous

First did I understand the question right?

7. anonymous

$\sqrt{12} = \sqrt{3*4} = 2*\sqrt{3}$

8. anonymous

is that okay? sqrt(4)=2 so we can "pull" that out.

9. anonymous

yes ! im tryinq to fiqure out what appLys to that # .

If the number does not have a straight forward square root, then it is irrational. Sqrt(2) and sqrt(3) are irrational. On the other hand sqrt(0.09) = 0.3, so that is rational.
