We know that a number that can be written as \frac{p}{q}, where p and q are integers and q \neq 0, is known as RATIONAL NUMBERS. Thus, the set of the rational numbers contains all integers and fractions. The set of rational numbers is denoted by Q. Therefore, N \subseteq W \subseteq Z \subseteq Q.

Integral Exponents
Exponents
If n is a positive integer (a whole number, i.e., a number without decimal part) and x is a number, then
The number x is called the base and n is called the exponent.
The most common ways of referring to are “ x to the nth power,”
“ x to the nth,” or “the nth power of x.”

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

3. A rational number is a real number that can be written as a ratio of two integers.
A rational number written in decimal form is terminating or repeating.
Any number which can be expressed in the form p/q where p and q are integers and q is not equal to 0.For
ex- 2/3 , -3/-2 , -4/2.
Every fraction is a rational number, but every rational number need not to be fraction. For ex- -4/7 , 0/3
are not fractions as fractions are part of whole which are always positive.
All the integers are rational numbers. Integers -50 , 15 , 0 can be written as, -50/1 , 15/1 , 0/1 respectively.
The numbers –p/q and p/-q represent same rational number.
A rational number p/q is said to be in standard form if q is positive and the integers ‘p’ and ‘q’ have their
highest common factor as 1.
The result of two rational number is always a rational number.
Every rational number has an absolute value which is greater than or equal to zero.
5. Property 2:-
If p/q is a rational number and m be any integer different from zero then
p/q = p*m/q*m.
Example :-
6. Property 3:-
If p/q is a rational number and m is a common divisor of p and q then
p/q= p m/q m
Example :-
7. Property 1:-
If two rational number have the same positive denominator, the
number with the larger numerator will be greater than the one with smaller
numerator.
Example :- .
8. Property 2:-
if two rational numbers have different denominator , then first make
denominators equal and then compare.
Or
Another method to compare two rational number p/q and r/s with unequal
denominator. It is assumed that q and s are both positive integers.
Example :-
9. Property 1:-
The sum remain the same even if we change the order of addends, ie.,
for two rational number x and y, x + y = y + x.
*This is commutative law of addition.
Example :-
same
10. Property 2:-
Sum of three rational numbers remain the same even after
changing the grouping of addends, ie., if x, y and z are three rational number
then (x + y) + z = x + (y + z).
*This is known as associative law of addition.
Example :-
same
11. Property 3:-
When zero is added to any rational ,the sum is the rational number
itself, ie., if x is a rational number, then 0 + x = x + 0 = x. zero is called the identity
element of addition.
Example :-
12. Property 4:-
Every rational number has an additive inverse such that their sum is
equal to zero. If x is a rational number, then –x is a rational number such that x + (-
x) = 0. –x is called additive inverse of x. it is also called negative of x.
Example :-
13. Property 1:-
For rational number x and y, x - y = y-x in general . In fact , x - y = -(y-
x), ie., commutative property does not hold true for subtraction.
Example :-
Not same
14. Property 2:-
For rational number x, y, z in general, (x - y) -z = x -(y - z), ie., The
associative property does not hold true for subtraction.
Example :-
Not same
15. Property 3:-
Identity element for subtraction does not exist.
Property 4:-
Since the identity for subtraction does not exist, the question for
finding inverse for subtraction does not arise.
Example :-
16. Property 1:-
Product of two number remain the same even if we change their
order, ie., If x and y are rational numbers, then :- x*y = y*x. This is commutative
law of multiplication.
Example :-
Product is same
17. Property 2:-
Product remains the same even when we change the grouping of the
rational numbers, ie., If x, y and z are rational numbers ,then:- (x * y)*z = x*(y * z).
This is associative law of multiplication.
Example :-
Product is same
18. Property 3:-
Product of rational number and zero is zero, ie., If x is any rational
number then:- x * 0 = 0 = 0*x.
Example :-
19. Property 4:-
One multiplied by any rational number is the rational number itself,
ie., If x is a rational number, then:- x*1 = 1*x = x, ie., 1 is the identity element
under multiplication.
Example :-
20. Property 5:-
If x, y and z are rational numbers, then:- x *(y + z) = x * y + x * z. This
is distributive law of multiplication.
Example :-
Product is same
21. Property 1:-
Division of a rational number by another rational number expect
zero ,is a rational number.
Example :-
22. Property 2:-
When a rational number (non zero) is divided by the same rational
number, the quotient is one.
Example :-
23. Property 3:-
when a rational number is divided by 1, the quotient is the same
rational number.
Example :-
24. Property 4:-
If x, y and z are rational numbers, then (x + y) z = x z + y z and
(x – y) z = x z – y z.
Example :-
Product is same
25. Property 5:-
If x and y are non zero rational numbers, then in general, x y= y x
ie., Commutative property does not hold true for division.
Example :-
Not same
26. Property 6:-
If x, y and z are non - zero rational numbers, then, in general (x y)
z = x (y z).ie., associative property does not hold true for division.
Example :-
Not same
27. Property 7:-
For three non zero rational numbers x, y, and z, x (y + z) = x y + x
z, ie., distributive property does not hold true for division.
Example :-
Not same
28. Property 8:-
If x and y are two rational numbers, then x + y is a rational number
between x and y . 2
Example :-
