Find the complement of the set given that
u = {x | x is in i and −3 ≤ x ≤ 11}.
(enter your answers as a comma-separated list.)
{x | x is in i and −2 ≤ x < 6}

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.
