find two unit vectors orthogonal to both <1, -1, 1> and <0, 4, 4> can ya run down through this problem please. there were square roots in the answer, i thought this was just dot product? thanks.

Now calculate the absolute value of the resulting vector: Divide the result by the absolute value to reduce the vector to the length 1:
thanks, ya was cross product not dot product. used (-4 -4) - (4-0) + (4-0) for -8, -4. 4 thankyou, especially for the breakdown on the rest of the problem.
