Factional exponents, in general, are not rational. For example, the length of the diagonal of a unit square, which is sqrt(2).

Does the set of rational number overlap the set of irrational numbers why?
By definition, the two sets do not overlap. This is because the irrationals are defined as the set of real numbers that are not members of the rationals.
Name set which -10 belongs Ex-whole integers rational?
Negative integers, integers, negative rationals, rationals, negative reals, reals, complex numbers are some sets with specific names. There are lots more test without specific names to which -10 belongs.
Is the set of all real numbers continuous and the set of all integers discrete?
Yes, every Cauchy sequence of real numbers is convergent. In other words, the real numbers contain all real limits and are therefore continuous, and yes the integers are discrete in that the set of integers only contains (very very few, with respect to the set of rationals) rational numbers, i.e. their values can always be accurately displayed unlike the set of reals which is dense with irrational numbers. It's so dense with irrationals in fact, that by comparison, the set of rationals can be called a null set, however that is a different topic.
Why the set of rationals does not form a group wrt multiplication?
All the elements in a group must be invertible with respect to the operation. The element 0, which belongs to the set does not have an inverse wrt multiplication.
Why is every rational number a real number?
There are rational numbers and irrational numbers. Real numbers are DEFINED as the union of the set of all rational numbers and the set of all irrational numbers. Consequently, all rationals, by definition, must be real numbers.
What is a set of rational numbers that begin at 0?
It could be the set denoted by Q- (the non-positive rationals) or Q+ (the non-negative rationals).
What set of numbers does -23 belong to?
Integers, rationals, reals, complex numbers, etc.
The number -4 is what set of numbers?
The number -4 belongs to the set of all integers. It also belongs to the rationals, reals, complex numbers.
Does the set of rational number overlap the set of irrational numbers why?
By definition, the two sets do not overlap. This is because the irrationals are defined as the set of real numbers that are not members of the rationals.
How are irrational numbers abbreviated?
There is not a specific abbreviation. The set is denoted by R - Q: the real numbers minus the rationals.
What is the set of all numbers containing zero as well as all postitive and negative numbers?
The answer depends on what do you mean by "all". It could be the set of all integers, the set of all rationals or the set of all reals.
What represents fractions?
Q represents the set of all rational numbers, Zrepresents the set of all integers so Q excluding Z, represents all rationals that are not integers.
Which sets does the number zero belong?
There are an infinity of possible answers: the integers, rationals, reals, complex numbers, the set {0,1,-3}, the set containing only the element 0;
What are subsets of rational numbers?
There are an infinite number of subsets: All rationals other than 1 All rationals other than 2, etc All rationals other than 1.1 All rationals other than 2.1, etc, etc. All integers
What set of numbers does 5.86 belong to?
The Rationals, the set {1, 3 , 5.86, sqrt(59), -2/3, pi2}, the reals numbers, numbers between 5 and 6, etc.
Name set which -10 belongs Ex-whole integers rational?
Negative integers, integers, negative rationals, rationals, negative reals, reals, complex numbers are some sets with specific names. There are lots more test without specific names to which -10 belongs.
Are there more rational number than irrational numbers?
There are more irrational numbers than rational numbers. The rationals are countably infinite; the irrationals are uncountably infinite. Uncountably infinite means that the set of irrational numbers has a cardinality known as the "cardinality of the continuum," which is strictly greater than the cardinality of the set of natural numbers which is countably infinite. The set of rational numbers has the same cardinality as the set of natural numbers, so there are more irrationals than rationals.
