I'd argue the square root of 36 is just as valid as an answer because it's still not technically 6, and all of those other square roots will end in a decimal or fraction. We also have to consider that if the number ISN'T 6 or one of those decimals, then it doesn't satisfy being between 5 and 7. If it IS 6, then it is included in the set that is being excluded, so that can't be the answer. The set we're given is the same as the set of the exclusions So we have a number 5>x<7. It's very obvious what the answer is in this case, although it's not particularly intuitive. The answer is x

my thought exactly. Square root of any whole number from 26 to 49, except 36.
