Answer 1

Question. Simplify using identities :

196 × 196 - 104 × 104 whole divided by

92

Answer:

The answer is 300.

Step-by-step explanation:

196 is given 2 times so we can write 196^2 same with 104.

Let 196 be a and 104 be b.

Converting into variable form

$( {a}^{2} - {b}^{2} )$

We know that

$( {a}^{2} - {b}^{2} ) = (a + b)(a - b)$

Now, putting values in (a+b) (a-b)

(196+104) (196-104)

300 × 92

27600

Now, dividing 27600 by 92, we get

300.

Answer 2

Answer:

196 is given 2 times so we can write 196^2 same with 104.

Let 196 be a and 104 be b.

Converting into variable form

( {a}^{2} - {b}^{2} )(a

2

−b

2

)

We know that

( {a}^{2} - {b}^{2} ) = (a + b)(a - b)(a

2

−b

2

)=(a+b)(a−b)

Now, putting values in (a+b) (a-b)

(196+104) (196-104)

300 × 92

27600

Now, dividing 27600 by 92, we get

300.
