# State whether the expression is meaningful. If not, explain why? If so, state whether it is a vector or a scalar: abca¯×(b¯.c¯) - Mathematics and Statistics

State whether the expression is meaningful. If not, explain why? If so, state whether it is a vector or a scalar:

bar"a" xx (bar"b".bar"c")

#### Solution

This expression is meaningless because bar"a" is a vector, bar"b"· bar"c" is a scalar and vector product of vector and scalar is not defined.
