Take the cross product, then normalize the result.
![\mathbf a\times\mathbf b=\begin{vmatrix}\mathbf i&\mathbf j&\mathbf k\\1&7&1\\1&11&1\end{vmatrix}=-4\,\mathbf i+4\,\mathbf k](https://tex.z-dn.net/?f=%5Cmathbf%20a%5Ctimes%5Cmathbf%20b%3D%5Cbegin%7Bvmatrix%7D%5Cmathbf%20i%26%5Cmathbf%20j%26%5Cmathbf%20k%5C%5C1%267%261%5C%5C1%2611%261%5Cend%7Bvmatrix%7D%3D-4%5C%2C%5Cmathbf%20i%2B4%5C%2C%5Cmathbf%20k)
This has norm
![\|\mathbf a\times\mathbf b\|=\sqrt{(-4)^2+4^2}=4\sqrt2](https://tex.z-dn.net/?f=%5C%7C%5Cmathbf%20a%5Ctimes%5Cmathbf%20b%5C%7C%3D%5Csqrt%7B%28-4%29%5E2%2B4%5E2%7D%3D4%5Csqrt2)
and so a unit vector orthogonal to both given vectors is
![\dfrac{\mathbf a\times\mathbf b}{\|\mathbf a\times\mathbf b\|}=-\dfrac1{\sqrt2}\,\mathbf i+\dfrac1{\sqrt2}\,\mathbf k](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathbf%20a%5Ctimes%5Cmathbf%20b%7D%7B%5C%7C%5Cmathbf%20a%5Ctimes%5Cmathbf%20b%5C%7C%7D%3D-%5Cdfrac1%7B%5Csqrt2%7D%5C%2C%5Cmathbf%20i%2B%5Cdfrac1%7B%5Csqrt2%7D%5C%2C%5Cmathbf%20k)
An equally correct answer would be the negative of this vector, since
![\mathbf b\times\mathbf a=-\mathbf a\times\mathbf b](https://tex.z-dn.net/?f=%5Cmathbf%20b%5Ctimes%5Cmathbf%20a%3D-%5Cmathbf%20a%5Ctimes%5Cmathbf%20b)
