Step-by-step explanation:
<h3>To click on the given statements which is true :</h3><h3>The three given statements are true as below </h3>
- It is impossible for a swap matrix and a replacement matrix to have the same determinant
- There is an elementary matrix whose determinant is 0.
- The n×n elementary matrix realizing the scaling of a single row by a factor of α has determinant αn.
<h3>Option 2),3) and 5) are correct</h3>
This is false because 3 times 3=9 and all of those are odd
odd nubmers are represented by 2n+1 where n= a natural number (whhole numbers and negatives)
so (2n+1) squared=(2n+1)(2n+1)=4n^2+4n+1
(a whole number times an even number yeilds an even number because an
even number is represented by 2n where n=a natrual number so 2n times
x=2nx which is still even.)
since n represents a whole number and a whole number times an even number (4) equals an even number, 4n^2 and 4n must be even, and even+even=even
that leavs the +1 at the end
we know that even+1=odd so therefor any odd number squared results in an odd nnumber
an example is 9, 3 times 3 or 3 squared
