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 .
Some are and some are not. For example, the square roots of 2.25, 3.61, 4, 4.84, 5.29, 6.76, 7.29, 8.41, 9, 10.89, 11.56, 12.25, 13.69, 14.44, 15.21, 16, 17.64, 18.49, 19.36, 20.25, 21.16, 22.09, 23.04, 24.5025, and 25 are all rational numbers. But the square roots of 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23, and 24 are irrational numbers. We believe, but can't prove easily, that there are more irrational square roots than rational ones.
15 is both rational, and an integer. is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
It can be. The square roots of 2.25 are -1.5 and 1.5: rational numbers.
√10 x √6 = 2√15 = 7.745966692
The numbers are: 8 times square root of 15 and 8 times the square of 15
It is irrational
irrational
It is 15 which is a rational number
The square root of 15 is an irrational number and it is about 3.873 rounded to three decimal places
If you mean the square root of 196/225 then it is 14/15 which is a rational number because it can be expressed as a fraction.
The square root of 15 is an irrational number
Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.
The square root of 225 is 15, which is a rational number.
The square root of 225 is 15, which is NOT an irrational number.
