ans=0;
how?
5^2-sqrt4=23;
6^2-sqrt16=32;
same
3^2-sqrt9=0..

A*A-SQUARE ROOT(B)
5-4=23
(ie) 25-2
8-1=63
(ie)64-1

like wise all
so ans is
3-81=9-9=0

(5)^2 - (2)^(1/2) = 25-2=23
simillarly......
3-81=(3)^2 - (81)^(1/2)=9-9=0

5² - √4 = 25 - 2 = 23
8² - √1 = 64 - 1 = 63
6² - √16 = 36 - 4 = 32
9² - √9 = 81 - 3 = 78
3² - √9 = 9 - 3 = 6

Therefore:
3² - √81 = 9 - 9 = 0
