Negative numbers don't have real square roots since a square is either positive or 0, so i will have both the positive square root and the imaginary one that is the answer i believe.
Step-by-step explanation:
A. [tex]\sqrt{-25}=5i\\\sqrt{25}=5[/tex]
B. [tex]\sqrt{-81}=9i\\\sqrt{81}=9\\[/tex]
C. [tex]\sqrt{-36}=6i\\\sqrt{36}=6[/tex]
D. [tex]\sqrt{-144}=12i\\\sqrt{144}=12[/tex]
E. [tex]\sqrt{-\frac{1}{4} } =\frac{1}{2} i\\\sqrt{\frac{1}{4} } =\frac{1}{2}[/tex]
F. [tex]\sqrt{-0.36}=0.6i\\\sqrt{0.36}=0.6[/tex]
