Express of the complex number in the form `a+ib`.
`[(1/3+i7/3)+(4+i1/3)]-(-4/3+i)`

Explanation

To express the complex number \([(1/3+i7/3)+(4+i1/3)]-(-4/3+i)\) in the form \(a + ib\), we will follow these steps:

### Step 1: Simplify the expression
We start with the expression:
\[ \left(\frac{1}{3} + i\frac{7}{3}\right) + \left(4 + i\frac{1}{3}\right) - \left(-\frac{4}{3} + i\right) \]
