Is AB 1 a BA?
Yes. 1/(a/b)=b/a. Because we know that any elements will be reciprocal when we have divided by 1. for example 1/(4/2)=2/4again we can divide and see the answer that is 1/2.
In which of the following sets a-B is equal to BA?
In which of the following sets A – B is equal to B – A? Explanation: A- B= B-A = Empty set.
What is AB equal?
The equality between A and B is written A = B, and pronounced A equals B. Two objects that are not equal are said to be distinct. For example: means that x and y denote the same object.
Which property is a b/b a?
The commutative property
The commutative property states that the change in the order of numbers for the addition or multiplication operation does not change the result. The commutative property of addition for two numbers ‘A’ and ‘B’ is A + B = B + A.
How do you find the difference in sets?
The difference of two sets, written A – B is the set of all elements of A that are not elements of B….For all sets A, and B and D we have:
- A – A =∅
- A – ∅ = A.
- ∅ – A = ∅
- A – U = ∅
- (AC)C = A.
- DeMorgan’s Law I: (A ∩ B)C = AC ∪ B. C
- DeMorgan’s Law II: (A ∪ B)C = AC ∩ B. C
Which set is not empty?
The set S = {1,4,5} is a nonempty set. The set of all real numbers is another example of a nonempty set. It contains an infinite number of elements, so it has more than one element and satisfies our definition.
Is AB BA give reason?
Answer:This is only applicable when a is equal to b. Step-by-step explanation:If a is not equal to b then the statement will not hold.
What is 1/(a/b) = 1*(b/a)?
And one more method we have is we can make 1/ (a/b)=1* (b/a). so 1* (b/a)=b/a. because multiplication of any number with 1 will give the answer as the number which we have multiplied. Yes. 1/ (a/b)=b/a.Because we know that any elements will be reciprocal when we have divided by 1.
What is the difference between a is equivalent to B?
A is equivalent to B means that values of A and B are very close to each other while A equal to B means that A has same value as B. Example-If A=0.98 and B=1 then A is equivalent to B but not equal to A.
What is ∴(a + B)(A – B) = A2-B2?
∴ (a + b) (a − b) = a 2 − b 2 The mathematical equation expresses that the product of sum and difference basis binomials, which contain the same terms is equal to the difference of them. It is used as a formula in mathematics. Hence, it is called an algebraic identity.
What is the value of a + B(A – B)?
(a + b) (a − b) = a 2 − b 2 It is read as the a plus b times a minus b is equal to the a squared minus b squared.
