Question

sqrt(-98) * sqrt(-50) = ?

Answer 1

\[\sqrt{-98}* \sqrt{-50}\\\sqrt{-2*49}* \sqrt{-2*25}\\7\sqrt{-2}* 5\sqrt{-2}\\35*-2\]

Answer 2

ok, so an online tutor from college wrote it out like this......
sqrt(-98) * sqrt(-50)=
sqrt(-1*98) * sqrt (-50)=
a(p*q)=a(p) * a(a)=
sqrt(-1) * sqrt(98) * sqrt(-1) * sqrt (50)
sqrt(98)=i *sqrt (50)=i
sqrt(49*2)=i *sqrt(25*2)=i and this is where i'm stuck
