OpenStudy (anonymous):

An irrational number is any real number that cannot be expressed as a ratio of integers

OpenStudy (anonymous):

irrational numbers are non-terminating and non-repeating decimals \[\sqrt{17}\]

OpenStudy (anonymous):

\[\frac1 6 = 0.16666666....\] which is non-terminating but repeating

OpenStudy (anonymous):

\[\sqrt{49} = 7\] and\[0.16\] is a terminating decimal number

OpenStudy (anonymous):

*correction 0.06

OpenStudy (anonymous):

so, D, i am sure...

OpenStudy (anonymous):

so \[\sqrt{17}\] will be the answer

OpenStudy (anonymous):

\[0.06=\frac6 {100} =\frac{3}{50}\] this kind of representation (0.06 in the form of 3/5) is called RATIONAL. ans this makes 0.06 (3/5) a rational number

OpenStudy (anonymous):

B is correct because 17 is a prime number. Square root of any prime number is irrational.

OpenStudy (anonymous):

correct

OpenStudy (anonymous):

0.06 is the ratio of 6 to 100, so it's rational
