Question

Solve sqrt-99(sqrt-7 minus sqrt -13)

Answer 1

\[\sqrt{-99}(\sqrt{-7} - \sqrt{-13})\]

?

Answer 2

yes. @LogicalApple in terms of i. sorry.

Answer 3

i was on my phone posting.

Answer 4

wait, no @logicalapple
\[\sqrt{-99}*(\sqrt{-7}-\sqrt{13})\]

Answer 5

Oh I see. Try rewriting sqrt(-99) as i sqrt(99) and sqrt(-7) as i sqrt(7)

Then distribute i sqrt(99):

\[i \sqrt{99} (i \sqrt{7} - \sqrt{13} )\]

Answer 6

\[3\sqrt{11}*(\sqrt{7}i - \sqrt{13})\]
@logicalapple

Answer 7

\[3i \sqrt{11} * (i \sqrt{7} - \sqrt{13}) = 3i^{2} \sqrt{77} - 3i \sqrt{143}\]
