Solution
The given numbers are rewritten as a(b+c) = a × b + a × c in the following manner:
(1) 9 (3 + 14) = 9 × 3 + 9 × 14
(2) 25 (23 + 16) = 25 × 23 + 25 × 16
(3)20 (58 + 109) = 20 × 58 + 20 × 109
(1) 9 (3 + 14) = 9 × 3 + 9 × 14
(2) 25 (23 + 16) = 25 × 23 + 25 × 16
(3)20 (58 + 109) = 20 × 58 + 20 × 109
