Question #fd348

Answer 1

`(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`.
