Answer 1

which ones?

Answer 2

Here It Is..

Answer 3

\[\sqrt{-128}=\sqrt{64\cdot 2\cdot -1}\] is the first one

Answer 4

second one is
\[\sqrt{64}\times \sqrt{2}\times \sqrt{-1}\]

Answer 5

the book has you walking through step by slow step probably more confusing than helpful i bet

Answer 6

next one is
\[8\cdot\sqrt{2}\cdot i\]

Answer 7

yess. very confusing.

Answer 8

and the final one i don't know. i guess they want
\[8i\sqrt{2}\] but that is really stupid because standard form is
\[8\sqrt{2}i\]

Answer 9

the whole point was to get you from
\[\sqrt{-128}\] to
\[8\sqrt{2}i\]
