Question

Can someone help me simplify the negative square root of -169?

Answer 1

\[-\sqrt{-169}\]

Answer 2

have you learned about \(\normalsize\it i\) yet?

Answer 3

\[\sqrt{-1}=i\]
So....
\[-\sqrt{-169} \rightarrow -i \sqrt{169}\]

Answer 4

@sleepyjess yea I have, but the negative outside of the square root was confusing me

@StudyGurl14 I would just factor 169 from there right?

Answer 5

@StudyGurl14 I was thinking it would be \(-\sqrt{169i}\)

Answer 6

No @sleepyjess because...
\[-\sqrt{-169} \rightarrow -\sqrt{-1\times169} \rightarrow -\sqrt{-1}\sqrt{169} \rightarrow -i \sqrt{169}\]

Answer 7

@StudyGurl14
If I was to factor this out, would I end up with \[-13i \sqrt{13}\]

Answer 8

@sleepyjess I like yhur poptart owl.

Answer 9

Nope. since
\[\sqrt{169} = 13\]

Answer 10

so...
\[-i \sqrt{169} = -13i\]

Answer 11
