If a→=i^-j^ and b→=j^+k^, then a→×b→2+a→.b→2= ___________ – InterviewSolution

1.	If a→=i^-j^ and b→=j^+k^, then a→×b→2+a→.b→2= ________________.
Answer» $If \vec{a} = \hat{i} - \hat{j} and \vec{b} = \hat{j} + \hat{k}, then {\|\vec{a} \times \vec{b}\|}^{2} + {\|\vec{a} . \vec{b}\|}^{2} =________________.$
