conditional statement: if x^2=25, then x=5

the options are
x=10
none,the statement is true
x=-5
x=-10
i think it’s C

Answer 1

yes, -5 *-5 = 25
so if x^2 = 25 then x is not necessarily +5

Answer 2

If x²=25

then x=±√25
=5 or -5

Counter example oppose the condition to the given example

So what does that tell you
