EMNA Q.43
0. If a, b, c, d, p and q are non-zero, unequal integers and (a+bi)/(c+di) equals
- Option : B
- Explanation : a + bi p c + di q qa + qbi = pc + pdi Equating real and imaginary parts. qa = pc and qb = pd. a = -P/q -c and b = (p/q)d * a²+b² (p²/q²)c + (p²/q²)d² p² ---- = ------------------- = -- c²+d² c²+d² q²
