Answer 2

Finding the square of the given number

We can find the square of 93 by applying the identity (a + b)² = a² + 2ab + b²

Now, 93 can be written as 90 + 3.

On applying the identity, we get,

93² = (90 + 3)² 

= (90)² + 2(90)(3) + (3)²

= 8100 + 540 + 9 

= 8649

Hence, using an identity, the square of 93 is 8649.
