Answer:

#(1 - (-1/3) = 4/3)/2 = 2/3# and #sqrt(2/3) = sqrt2/sqrt3 = sqrt6/3#

Explanation:

Take the # - ( -1/3)# and turn it into #1/3#

Then, turn the #1 1/3# into #4/3#

When you divide #4/3# by #2# it gets you #2/3#

Next, using that one square root identity, #sqrt(2/3)# becomes #sqrt2/sqrt3#

Finally, remove the radical on bottom by multiplying by #sqrt3/sqrt3# to turn #sqrt2/sqrt3# into #sqrt6/3#.
