\[\sqrt{-25}=\sqrt{25} \sqrt{-1}\]

Answer 6

the square root of a negative number -1 is i. since -25=25*-1,sqrt of -25=sqrt of 25*-1.
square root of 25=5, square root of -1=i .5*i=5i. negate. -5i

Answer 7

\[\sqrt{-25} = \sqrt{-1}\sqrt{25} = 5i\]

Since you had \[-\sqrt{-25} = -5i\]

Answer 8

Thanks fellas.

Answer 9

\[\large -\sqrt{-25}\]


\[\large -\sqrt{-1*5^2}\]


\[\large -\sqrt{-1}*\sqrt{5^2}\]


\[\large -i*5\]


\[\large -5i\]


Note: \[\large i=\sqrt{-1}\]


So \[\large -\sqrt{-25}=-5i\]
