1...If A ,B are two n- rowed sqaure matrices having ranks 1 and 2 respectively. find the rank of AB.
2..Constract a skew-symmetric matrix of rank 5.
3..if A is a non-zero coulmn and B is a non-zerorow matrix,then prove rank(A_B)=1.
4..State and prove navier-stroke,s equation.
5..Let X be the matric space whose points are the rational numbers, withthe metric d(x,y)=mod(x-y). what is the completion of this space.
