" 5."ab^(7)+ba^(7)

The degree of the polynomial 3a ^(2) + 4b ^(3) - 5 ab ^(3) + 7 - 5a ^(7) b ^(5) is

Factorise : 5a^(2) - b^(2) - 4ab + 7a - 7b

Identify like terms in the following: 4ab, 7a, 8b, -3a^(2)b^(2), - 4ba, -50b, - 75, 15b^(2)a^(2), - 7a^(2), 45, 150a, 70ba, 10a^(2)b, - 15ab^(2), 3ba^(2), - 21a^(2), 7b^(2)a .

In the algebraic expression 2a^(2)b+3ab^(2)-7ab-4ba^(2), we have 2a^(2)b and -4ba^(2) as like terms,whereas 3ab^(2) and 7ab are unlike terms.

If A=[[7,-2],[-1,2],[5,3]] and B=[[-2,-1],[4,2],[-1,0]] then find AB^(T) and BA^(T)
