how to solve sqrt(-8.3)sqrt(1 - i8)?
i try to solve it.. but got the wrong answer..
sqrt(-8.3)sqrt(1 - i8) = sqrt[(8.3i^2)(1 - 8i)]
= sqrt (8.3i^2 - 66.4i)
= 2.88i + 8.15
the answer should be.. 5.41 + i6.13

sorry... typo... from my calculation.. it should be 2.88i - 66.4
i get it from sqrt (8.3i^2) and sqrt 66.4i)
