simplify if possible sqrt1/2 times(sqrt8+sqrt2) is the answer 3
------------------------
sqrt%281%2F2%29%2A%28sqrt%288%29+%2B+sqrt%282%29%29
= sqrt%281%2F2%29%2A%282sqrt%282%29+%2B+sqrt%282%29%29
= sqrt%281%2F2%29%2A%283sqrt%282%29%29
= 3%2Asqrt%28%281%2F2%29%2A2%29%29
= 3
--------
Note: sqrt(1) can also be -1
--> -3
