If `x=a+bi` is a complex number such that `x^2=3+4i and x^3=2+11i`, where `i=sqrt-1`, then `(a+b)` equal to

Explanation

To solve the problem, we need to find the values of \( a \) and \( b \) from the complex number \( x = a + bi \) given that \( x^2 = 3 + 4i \) and \( x^3 = 2 + 11i \).

### Step-by-Step Solution:

1. **Express \( x \) in terms of \( x^2 \) and \( x^3 \)**:
\[ x = \frac{x^3}{x^2} \]
