Find the union of the following sets, namely ${-1, -7, 3 \sqrt{5}, -9, 7, \frac{11}{\sqrt{2}}, \frac{23}{7}} \cup {-6, -9.888, -7, -9, 4 \sqrt{5}, \frac{23}{7}, \frac{11}{\sqrt{2}}, 9}$.

import math

fst = set((-1, -7, 3*math.sqrt(5), -9, 7, (11/(math.sqrt(2))), (23/7),))
snd = set((-6, -9.888, -7, -9, 4*math.sqrt(5), (23/7), (11/(math.sqrt(2))), 9,))
print(fst.union(snd))
