Consider the vectors me ijzvu3+,i ) -8km dpl6nqq5y3j6b;n hx/fnb bg07fcpnv9;given by $\mathbf{u}=\mathbf{i}+3 \mathbf{j}-4 \mathbf{k}$ and $ \mathbf{v}=a \mathbf{i}+c \mathbf{k}$ , where a and c are constants.
It is given that $\mathbf{u} \times \mathbf{v}=3 \mathbf{i}+b \mathbf{j}-6 \mathbf{k}$ , where b is a constant.
1. Find the value of each of the constants a, b and c . a = b = c =
2. Hence find the Cartesian equation of the plane containing the vectors $\mathbf{u}$ and $\mathbf{v}$ and passing through the point $ \mathrm{P}(3,1,0)$ . x-2y-2z =
