Question

253²-247² evaluate using the identity a² - b²=(a+b) (a-b)​

Answer 1

Answer:

3000

Step-by-step explanation:

$253^{2}$ - $247^{2}$

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

Solution:

= (253 + 247) (253 - 247)

=  (500) (6)

= 500 * 6

= 3000

Answer 2

Answer:

Answer:

3000

Step-by-step explanation:

-

Using identity:  -  = (a + b) (a - b)

Solution:

= (253 + 247) (253 - 247)

=  (500) (6)

= 500 * 6

= 3000
