namaskar this video topic Class 11 Chapter 5 Complex Number and Quadratic Equation Miscellaneous Exercise Question no.4 Answer If x - iy = √(a - ib)/(c - id) Prove that: (x² + y²)² = (a²+ b²)/(c² + d²). https://jnehranehra.blogspot.com/2024... If x-iy = √a-ib/c-id Prove that (x²+y²)²=a²+b²/c²+d² If x-iy = sqrt[(a-ib)/(c-id)] prove that (x2 + y2)2 = (a2 + b2)/(c2 + d2) Misc 4 - If x - iy = root (a - ib)/(c - id) prove (x2 + y2)2 vid566 thanks watch this video have a nice day
