Answer:
Option A.
Step-by-step explanation:
The given expression is
[tex]-25[/tex]
According to the reflexive property of equality, all values are equal to itself.
a = a
where, a be any real number.
Using the reflexive property we can say that
[tex]-25=-25[/tex]
It means -25 is equal or equivalent to -25.
Therefore, the correct option is A.
Note: If the given expression is [tex]\sqrt{-25}[/tex], then
[tex]\sqrt{-25}=\sqrt{25}\sqrt{-1}[/tex] [tex][\because \sqrt{ab}=\sqrt{a}\sqrt {b}][/tex]
[tex]\sqrt{-25}=5i[/tex] [tex][\because \sqrt{-1}=i][/tex]
Then the correct option is B.
