Step 1 of 20
The objective is to determine whether the given statements arepropositions and to provide the truth value of eachproposition.
A sentence that has exactly one truth value is called asProposition. The truth value is either true, denoted by T,or false denoted by F.
Step 2 of 20
a)
Consider the sentence “What time is dinner?”
This is not a proposition because it is a question.
Step 3 of 20
b)
Consider the sentence “It is not the case that is not a rational number.”
As the given sentence has exactly one truth value, so thesentence is a proposition.
The sentence is the negation of is not a rational number, thus the sentence is is a rational number.
But observe that, is an irrational number.
Thus, the truth value of the sentence is False.
Step 4 of 20
c)
Consider the sentence “isa rational number.”
Observe that the truth value of the sentence varies with thevalues of . This is not a proposition.
The truth value of the sentence can be determined asfollows:
Suppose
Then the value of is,
Thus, and 1 is a rational number.
Therefore, the truth value is true.
- is not a proposition. However, it doesn't have a truth value. See the definition of proposition.
- example, let ×=pi then it will be irrational.
Step 5 of 20
Suppose
Then the value of is,
Thus, and is an irrational number.
Therefore, the truth value is false.
Thus, the sentence has more than one truth value.
Hence, the sentence is not a proposition.
Step 6 of 20
d)
Consider the sentence “isa real number.”
Observe that the truth value of the sentence varies with thevalues of and . This is not a proposition.
The truth value of the sentence can be determined asfollows:
Suppose
Then the value of is,
Thus, and 13 is a real number.
Therefore, the truth value is true.
Step 7 of 20
Suppose
Then the value of is,
Thus, and is a complex number.
Therefore, the truth value is false.
Thus, the sentence has more than one truth value.
Step 8 of 20
Step 9 of 20
e)
Consider the sentence “Either is rational and 17 is a prime, or and 81 is a perfect square.
This is a proportion.
The truth value of the sentence can be determined asfollows:
Let is rational.
Then the proposition is equal to
Step 10 of 20
As is rational, so P is false.
Therefore, is false.
As , so R and S are true.
Therefore, is true.
Thus, the truth value of is true.
As the sentence has exactly one truth value, so the sentence isa proposition and its truth value is True.
Step 11 of 20
f)
Consider the sentence “Either 2 is rational and is irrational, or is rational.
This is a proportion.
The truth value of the sentence can be determined asfollows:
Let is rational.
Then the proposition is equal to
Step 12 of 20
As is rational, so P is true.
As is irrational, so Q is true.
Therefore, is true.
As , so R is false.
Thus, the value of is true.
Therefore, the truth value of the proposition istrue.
As the sentence has exactly one truth value, so the sentence isa proposition and its truth value is True.
Step 13 of 20
g)
Consider the sentence “Either is rational and is rational, or there are exactly four primes less than 10.
This is a proportion.
The truth value of the sentence can be determined asfollows:
Let is rational.
Then the proposition is equal to
Step 14 of 20
As is rational, so P is false.
As is rational, so Q is true.
Therefore, is false.
As , so R is true.
Thus, the value of is true.
Step 15 of 20
Therefore, the truth value of the propositionis true.
As the sentence has exactly one truth value, so the sentence isa proposition and its truth value is True.
Step 16 of 20
h)
Consider the sentence “is rational, and either ”
This is a proportion.
The truth value of the sentence can be determined asfollows:
Let is rational.
Then the proposition is equal to
Step 17 of 20
As is rational, so P is true.
As , so Q is true.
As , so R is false.
Thus, the value of is true.
Therefore, the truth value of the proposition istrue.
As the sentence has exactly one truth value, so the sentence isa proposition and its truth value is True.
Step 18 of 20
i)
Consider the sentence “It is not the case that 39 is prime, orthat 64 is a power of 2.”
This is not a proportion.
The truth value of the sentence can be determined asfollows:
Let is prime.
is a power of 2.
Then the proposition is equal to
Step 19 of 20
As is prime, so P is false.
Asis a power of 2, so Q is true.
Therefore, is true.
Thus, the value of is false.
Therefore, the truth value of the proposition isfalse.
As the sentence has exactly one truth value, so the sentence isa proposition and its truth value is False.
Step 20 of 20
j)
Consider the sentence “There are more than three falsestatements in this book, and this statement is one of them.”
This is not a proportion.
The sentence is a paradox.
Hence, the sentence is not a proportion.
- proposition is spelt wrong
