We have an algebraic expression and we have to express it in the form of a complex number.
To do that we have to take into account the definition of the imaginary number i:
We can now work on the expression to find the complex number it represents:
Then, if we define the complex number as a + bi, then a=0 and b = โ(3/10).
Answer: a=0 and b = โ(3/10)
