Options

• 9964

• 9984

• 9994

Answer 1

96 × 104 is equal to 9984.

Explanation:

To calculate 96 × 104, use the identity (a – b)(a + b) = a² – b² by expressing 96 and 104 as (100 – 4) and (100 + 4) respectively.

96 × 104 = (100 – 4)(100 + 4)

96 × 104 = 100² – 4²

96 × 104 = 10000 – 16

96 × 104 = 9984
