Answer 1

Answer:

The required answer is 0

Step-by-step explanation:

• 5 - 4 = 23

23 is obtained by : 5² - √4

                             = 25 - 2 = 23

• 8 - 1 = 63

63 is obtained by : 8² - √1

                             = 64 - 1 = 63

• 6 - 16 = 32

32 is obtained by : 6² - √16

                             = 36 - 4 = 32

• 9 - 9 = 78

78 is obtained by : 9² - √9

                             = 81 - 3 = 78

• 3 - 9 = 6

6 is obtained by : 3² - √9

                          = 9 - 3 = 6

Similarly, for 3 - 81 : Subtracting square root of second number from square of first number

⇒ 3² - √81

= 9 - 9 = 0

Hence, the required answer is 0
