WebApr 1, 2024 · If (a + ib) (c + id) (e + if) (g + ih) = A + iB, then show that (a2 + b2) (c2 + d2) (e2 + f2) (g2 + h2) = A2 + B2. Solution: Given: (a + ib) (c + id) (e + if) (g + ih) = A + iB Therefore, (a + ib) (c + id) (e + if) (g + ih) = A + iB = (a + ib) × (c + id) × (e + if) × (g + ih) = A + iB On squaring both sides, we get WebFurther, g(x + iy) = f(a + ib) ⇒ g(x – iy) = f(a – ib).
