BA=B
MULTIPLY BY B...
(BA)B=B2
B(AB)=B2 (BECOZ matrix product is associative...)
SINCE AB=A
BA=B2
SINCE BA=B...
THEREFORE...
B=B2
If A and B are two matrices such that AB=A and BA=B then B2 equals
(a)B (b)A (c)1 (d)0
Plz give soln also.
BA=B
MULTIPLY BY B...
(BA)B=B2
B(AB)=B2 (BECOZ matrix product is associative...)
SINCE AB=A
BA=B2
SINCE BA=B...
THEREFORE...
B=B2
THIS FOR NISHANT BHAIYA...
bhaiya itne time baad online kissi ko answer kiya hai ek pink de dena plzzzz....
