Question

simplify 3+j2/1-j3

Answer 1

Multiply both terms by the conjugate of 1-j3 (which is 1 + j3) as a first step.

Answer 2

by "both terms" kropot72 means the numerator and the denominator.

Answer 3

@asnaseer thank you!
@khadeejah can you multiply numerator and denominator by 1 + j3 ?

Answer 4

@khadeejah do you why kropot72 is asking you to multiply numerator and denominator by the complex conjugate of the denominator?

Answer 5

When you do the whole expression becomes:
3 +( j2)/10{1 + j3}

Answer 6

As you can see there is no longer a complex number as a denominator.
The expression further simplifies to the following:
3 + j/5 - 3/5 = 1/5(12 - j)
