" 11.If "A=[[b,b^(2)],[-a^(2),-ab]]," then "A" is "

If a*b= a^(2)+b^(2)-ab-5 on set Z then 4*5=

If the binary operation on ZZ is defined by a**b=a^(2)-b^(2)+ab+4, then the value of (2**3)**4 is --

If the binary operation * is defined a * b=a^(2)-b^(2)+ab+4 then (2 * 3) * 4 is :

If * defined as a * b =a^(2)+b^(2)-ab then 3 * (4 * 2) is

If ** is defined by a ** b =a^(2) + b^(2) + ab +1 , then (2 ** 3) ** 2 is

If a ** b =a^(2)b^(2)-ab then 3 ** (1 **1) ________

If a * b = a^(2) + b^(2) and a.b = a^(2) - b^(2) , then the value of (5 * 2).25 is

If A = [[2,2],[4,0]] and B = [[1,1],[2,1]] , then: (a)abs(A)=2^3abs(B) (b)abs(A)=2^2abs(B) (c)abs(A)=abs(B) (d)abs(A)=2^4abs(B)

(a + 2b)^(2) - (a - 2b)^(2) = 8ab
