Answer 2

Step-by-step explanation:

→Question :

Q. Evaluate using identities 105 x 95

→Explanation :

We can write 105 = 100 + 5

&

95 = 100 - 5 .

→Identity used :

• ( A + B ) ( A- B ) = A² - B²

So,

Case -1 i.e 105 = 100+5

→ (100)² - (5)²

→ 10000 -25

→9975

Case -2 i.e 95= 100-5

→(100)² - (5)²

→10000-25

→9975

→Answers :

The evaluation of 100 × 95 = 9975.
