Tell whether each number is a real number, rational number, irrational, interger, or whole number, and then order then from least to greatest.
( Square root sign) 49, 8, -( square root sign) 4, and -3.
I will be happy to check your work.
I don't understand how to do it, that's the thing I know that 8 is a whole number, and that the square root of four is 2, and that's a whole number, and the aquare root of 49 is 7, that's a whole number too, and -3 is an interger.
What you don't know is what a rational/irrational number is.
Review those definitions, and you have it, then order them

All the whole numbers are rational because they can be written as a fraction, and irrational are the ones that can't be written as fractions. I understand that part.
Ok,then say so as the problem dictates, you have done everything except order them least to greatest
To determine the nature of each number and order them from least to greatest, we need to understand the definitions of real numbers, rational numbers, irrational numbers, integers, and whole numbers.
1. Real Numbers: Real numbers include all numbers on the number line, both rational and irrational numbers.
2. Rational Numbers: Rational numbers are numbers that can be expressed as fractions, where the numerator and denominator are integers, and the denominator is not zero.
3. Irrational Numbers: Irrational numbers are numbers that cannot be expressed as fractions, and their decimal representations neither terminate nor repeat.
4. Integers: Integers are whole numbers, both positive and negative, including zero.
5. Whole Numbers: Whole numbers are non-negative integers, including zero.
Now, let's determine the nature of each number and order them from least to greatest:
-3: This is an integer and a whole number.
-(√4): This is an irrational number since the square root of 4 is a positive rational number (2), and adding a negative sign makes it irrational.
8: This is a rational number since it can be expressed as the fraction 8/1.
√49: This is a rational number since the square root of 49 is a positive rational number (7).
Now, let's order them from least to greatest:
-3, -(√4), √49, 8
