Question

Simplify.

Answer 1

\[\LARGE \sqrt{-16} \times \sqrt{-18} \]

Answer 2

Is that all?

Answer 3

Cos that's not an option...

Answer 4

are the options with i, where i = sqrt(-1)?

Answer 5

yes

Answer 6

sqrt(-16)*sqrt(-18) = (i)sqrt(16)*(i)sqrt(18) = (i^2)sqrt[(16)(18)] = -sqrt(288) = sqrt(36*4*2) = -(6)(2)sqrt(2) = -12sqrt(2) or (i^2)12sqrt(2)
