Question

question: write the complex number in standard form
square root of -16

Answer 1

would it be the same for square root of -121?

Answer 2

\[\sqrt{a*b}=\sqrt{a}*\sqrt{b}\]

Answer 3

sqrt(-16) = sqrt(16)sqrt(-1) = 4i

Answer 4

the answer is you factor the -1 out of the equation: \[\sqrt{-16}=\sqrt{-1}*\sqrt{16}\]

Answer 5

if i=\[\sqrt{-1}\] then the final answer is 4i

Answer 6

can you draw it step by step

Answer 7

this is not something you draw
sqr(ab) = sqrt(a)*sqrt(b)
so the steps are
sqrt(-16) = sqrt(16)sqrt(-1) = 4i
