Question
Out of the four given equations, the first three are
solved based on a certain system. Find the correct answer for the unsolved fourth equation on the same basis. 3 & 7 = 64 6 & 6 = 109 9 & 8 = 217 10 & 9 = ?Solution
Given equations, 3 & 7 = 64 → 3 × 7 × 3 + 1 = 64 6 & 6 = 109 → 6 × 6 × 3 + 1 = 109 9 & 8 = 217 → 9 × 8 × 3 + 1 = 217 For the fourth equation: 10 & 9 → 10 × 9 × 3 + 1 = 271
