The complex number is 5 / 1 + I ^ 3, which is in the form of a + bi. That's the third power of I. don't read it wrong. The final answer is 1-i,
i³=i*i²=-i
So the original formula = 5 / (1-I)
=5(1+i)/(1+i)(1-i)
=(5+5i)/(1+1)
=5/2+5i/2
The answer is wrong
Multiply the conjugate complex number of denominator to get 5 / 2 + 5I / 2
The answer is no, yes

The angle problem of complex number in the form of S = a + bi
For example, z = 15 + J20 = 25 ∠ 53.13 ° this result is how to get the calculation process and its formula!
The complex z = a + BJ is transformed into the trigonometric R (COS θ + jsin θ) which can be abbreviated as R ∠θ, where the module r = √ (A & # 178; + B & # 178;); the complex angle θ is solved by Tan θ = B / A and takes its value (principal value) in the range of 0 ≤ θ ＜ 360 °. For example, 1. Complex 15 + 20j: ∵ r = √ (15 & # 178; + 20 & # 178;) = 25, and θ takes 15 and 20 as two direct values
