For the most tasks WA1 means your program can't even solve sample.

Have you tried to run it locally? It's clearly visible it doesn't work.

There is only 2 numbers in output so your program processed first input line only.

    string = f.read()

from re import *
from math import sqrt

result = findall('[0-9]+', string)
result.reverse()

for i in result:
    print('{:.4f}'.format(sqrt(int(i))))
