Is it always true that
√a × √b = √ab ?
Most students think YES. But the truth depends on whether we are working in real numbers or complex numbers.
In this video, we carefully test the identity in different cases:
• When a ≥ 0 and b ≥ 0
• When one number is negative
• When both numbers are negative
This is a must-watch for students preparing for Olympiad, JEE, and higher mathematics.
