List:  (approx 3.32), -0.4 (repeating), 3.41, (-0.45)

Ordered from Least to Greatest:
(-0.45)
-0.4 (repeating)
(approx 3.32)
3.41

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
