Answer:

9409

Step-by-step explanation:

Let's rewrite 97 as 100 - 3.

Identity used :

(a - b)² = a² - 2ab + b²

Now, evaluating the expression :

⇒ (100 - 3)²

⇒ (100)² - 2(100)(3) + (3)²

⇒ 10000 - 600 + 9

⇒ 9400 + 9

⇒ 9409

Evaluate

( 97 )^2 evaluate of the following by using identities.

Evaluate Solution:

  • = 100 - 3² close parenthises.
  • = (100)² - 2 (100)(3) + (3)²
  • = 10,000 - 600 + 9
  • = 10,000 - 600
  • = 9400
  • = 9400 + 9
  • = 9409
