If p & q = p2 + 4pq – q2 then find the value of (3 & 6) + (4 & 5).1). 982). 1063). 1164). 126 |

Answer» If p & q = p2 + 4PQ - q2 Put the value p = 3 and q = 6 ⇒ 3 & 6 = 32 + 4 × 3 × 6 – 62 = 9 + 72 – 36 = 45 Similarly, we put p = 4 and q = 5 ⇒ 4 & 5 = 42 + 4 × 4 × 5 – 52 = 16 + 80 – 25 = 71 ∴ (3 & 6) + (4 & 5) = 45 + 71 = 116 |
