simplify
3i - 2i^2 + 3
DIvided by
the square root of -16 - the square root of -2 times the square root of -2
---------
[3i -2i^2 + 3]/[sqrt(-16) -(sqrt(-2)*sqrt(-2))]
=[3i + 2 + 3]/[4i -(isqrt(2))^2]
=[3i+5]/[4i - (-2)]
=[5+3i]/[2+4i]
Multiply numerator and denominator by 2-4i to get:
=(5+3i)(2-4i)/20
=(22-14i)/20
=(11-7i)/10
