Nice question!
The square root of (any number that isn't a perfect square) is irrational.
No Prime number is a perfect square.
So the square root of any prime number is irrational.
NO!!! '29' is a Prime Number. The square roots of prime numbers are irrational sqrt(29) = 5.385164807.... NB Irrational numbers are those where the decimals go to infinity AND there is no regular order in the decimal digits.
A rational number can be expressed as the ratio of two integers (the number one does not count). An irrational number cannot. The square root of 5 cannot be expressed as the quotient of two integers. This assertion is by experience that the square root of a prime number is irrational. There are several methods to prove the irrationality -- look for them elsewhere. For the sake of curiosity, my calculator gives the following result for it: 2.2360679774997896964091736687312762354406183596115257242708972454105209256378048994144144083787822749695081761507737835042532677244470738635863601215334527088667781731918791658112766453226398565805357613504175337850034233924140644420864325390972525926272288762995174024406816117759089094984923713907297288984820886415426898940991316935770197486788844250897541329561831769214999774248015304341150359576683325124988151781394080005624208552435422355561063063428202340933319829339597463522712013417496142026359047379... You can say that it is irrational by looking at the inexact answer.
No. Square roots of whole numbers that don't result in whole numbers (e.g. the square root of 64 is 8), are considered to be "irrational numbers".
Yes. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
IRRATIONAL sqrt(15) = sqrt(3 x 5) =sqrt(3) X sqrt(5) Since the 'square roots' of prime numbers , '3' & '5' in this case, are irrational , then the square root od '15' is irrational .
The square root of the prime number 19 is an irrational number
The square root of 169 is 13 which is a rational and also a Prime number
The square root of 121 is 11 which is a rational number and it is also a prime number
17 is a prime number with no factors other than itself and 1 therefore minus square root of 17 is an irrational number.
'47' is a prime number, so it does not have a rational square root. sqrt(47) = 6.8556546... to 9 d.p. An irrational number which cannot be converted to a quotient; that is made into a fraction. NB The square roots of prime numbers are irrational.
No. 19 is a prime number, and all prime numbers have irrational roots.
It is a rational number and also a prime number
sqrt(45) = sqrt(9 x 5) => sqrt(9 X 5) = sqrt(9) X sqrt(5) sqrt(9) = 3 Rational However sqrt(5) = 2.236067977..... which is Irrational. Remember Rational X Irrational = Irrational Hence sqrt(45) is irrational NNB The square roots of Prime number , '5' being a prime, are irrational.
No because the square root of any prime number is irrational inasmuch that it can't be expressed as a fraction.
2 is a rational number and it is also a prime number
It is rational. It is a whole number so it cannot be irrational.
NO!!! '29' is a Prime Number. The square roots of prime numbers are irrational sqrt(29) = 5.385164807.... NB Irrational numbers are those where the decimals go to infinity AND there is no regular order in the decimal digits.
