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)
