Answer 1

Answer:

Step-by-step explanation:

Using the property of square find the value of-

a) 24^2 - 23^2

b) 50^2- 49^2

c) 105^2- 104^2

A^2 -B^2 = (A+B)(A-B)

24^2 - 23^2

= (24+23)(24-23)

= 47 * 1

= 47

b) 50^2- 49^2

= (50+49)(50-49)

= 99 * 1

= 99

c) 105^2- 104^2

= (105+104)(105-104)

= 209*1

= 209
