Question 65725
Simplify
square root of -16
=4I

 - the square root of 3 times the square root of 3
=-[SQRT(3*3)]
=-3

 - the square root of -4 times the square root of -4 
=-(2I)(2I)
=-4I^2
=-4(-1)
=4

+ 3i - 3i^2 + 3i^3
=3I-3(-1)+3I(I^2)
=3I+3-3I
=3
Simplify
=4I-3+4+3
=4I+4


square root of -16 - the square root of 3 times the square root of 3 - the square root of -4 times the square root of -4 + 3i - 3i^2 + 3i^3
