Answer: 9120
Step-by-step explanation:
Given, 95 × 96
Given, expression can be written as
(90 + 5)(90 + 6)
Let, x = 90, a = 5 and b = 6
Using identity, (x + a)(x + b) = x2 + (a + b) x + ab
(90 + 5)(90 + 6)
= 902 + (5 + 6) × 90 + (5 × 6)
= 8100 + (11 × 90) + 30
= 8100 + 990 + 30
= 9090 + 30
= 9120
hope it's right
