A homogeneous equation is always consistent. A. True. A homogenous equation can be written in the form Axequals0, where A is an mtimesn matrix and 0 is the zero vector in set of real numbers R Superscript m. Such a system Axequals0 always has at least one nontrivial solution. Thus a homogenous equation is always consistent. B. True. A homogenous equation can be written in the form Axequals0, where A is an mtimesn matrix an

answer:

sometimes

*i think

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

where are the choices?
