Evaluate: 297 × 303.

Correct option is A

Given :

297 × 303.

Solution:

Notice that both numbers are close to 300, so we can use the identity for multiplying numbers close to a base:

​$$(a - b)(a + b) = a^2 - b^2$$​​

Let a = 300 and b = 3. This gives: 

​$$297 = 300 - 3 \quad \text{and} \quad 303 = 300 + 3$$ 

Now, apply the difference of squares identity: 

​$$297 \times 303 = (300 - 3)(300 + 3) = 300^2 - 3^2$$ 

​$$=90000−9=89991$$ 

Thus,  297 × 303 = 89991
