Question

Please anyone help and explain!

Answer 1

Okay, now first you simply the sqrt(-3) and sqrt (-39)
that gives you. i(sqrt3)*i(sqrt39)
Re arranging, it is i*i*sqrt(3*39)
Clear here?

Answer 2

yes, clear. thank you

Answer 3

Now the solution comes as -3sqrt(13)

Hope that helps.

Answer 4

\[\sqrt{-3}\sqrt{-39}=i \sqrt{3}(i \sqrt{39})=i^2\sqrt{3(3)(13)}=-3\sqrt{13}\]
