Answer 1

Example:

5^2 = 25
Square root of 4 = 2

So 25 – 2 = 23

Similarly we get the other number;

64 – 1 = 63;

36 – 4 = 32;

81 – 3 – 78;

9 – 3 = 6;

Hence in the last equation we have square of 3 minus square root of 81;

i.e 9 – 9 = 0

Hence the answer is “0”

Answer 2

Answer:

The required answer is zero.

Step-by-step explanation:

Given,

5 - 4 = 23

8 - 1 = 63

6 - 16 = 32

9 - 9 = 78

3 - 9 = 6

3 - 81 = ?

Let,

$(5)^{2} - \sqrt{4} = 25 - 2 = 23\\(8)^{2} - \sqrt{1} = 64 - 1 = 63\\(6)^{2} - \sqrt{16} = 36 - 4 = 32\\(9)^{2} - \sqrt{9} = 81 - 3 = 78\\(3)^{2} - \sqrt{9} = 9 - 3 = 6$

If we follow the same formula,

then,

$(3)^{2} - \sqrt{81} = 9 - 9 = 0$

Thus the required value is 0.
