No. 19 is a prime number, and all prime numbers have irrational roots.
Rational , because it can be converted to a fraction. 7.76 = 7 76/100 = 7 38/50 = 7 19/25 NB Irrational numbers cannot be converted tpo a quotient. 'pi = 3.1415936.... ' it the most famous irrational number. When you are given pi = 3.14' in school , this is only an approximation.
Rational!!!! Consider ALL numbers to be rational , except those decimals that gor to infinity AND there is no regular order in the decimal digits. Rational ; 2.33333..... Because the decimals are in a regular order. Irrational ; 3.141592.... Because the decimals are in an irregular order. The mathematical definition of irrational numbers that they cannot be converted to a quotient(fraction). NB The three or more stops after the last decimal is the mathemtical indication that it recurs to inifinity. If no stops are shown, then it is deemed to be a terminal decimal. e.g. 2.333 is a terminal decimal 2.33333..... is a decimal recurring to inifity. NNB pi = 3.141592... is the most well known irrational number. However, the 'Square Roots' of prime numbers are also irrational e.g. sqrt(2) = 1.414213562.... sqrt(19) = 4.358898944....
Yes, they are.
-- Any number that you can completely write down using digits, and a decimal point or fraction bar if needed, is rational. -- A rational number is defined as one that can be written as a fraction using whole numbers. -19 can be written as the fraction -19/1 .
It is a whole number so it is rational.

The square root of the prime number 19 is an irrational number
It is a rational number because it can be expressed as a fraction in the form of -19/1
No. √19 is an irrational number.
It is a whole number so it is rational.
-19 is a rational number, since it can be expressed in fraction form (-19/1).
Yes because all fractions are rational numbers whereas irrational numbers can't be expressed as fractions.
No because 19 is a whole number which means that it is a rational number
3.8 is a rational number because it can be expressed as a fraction in the form of 19/5
The number 19, like all integers, is a rational number. Only certain types of decimal expansions can be irrational.
No. 19 is a prime number, and all prime numbers have irrational roots.
