" 13.यदि "A=[[a,b],[b,a]]" और "A^(2)=[[alpha,beta],[beta,alpha]]" तब "

If A=[[a , b] ,[ b , a]] A^(2)=[[alpha , beta] ,[ beta , a]] then

If A=[(a,b),(b,a)]and A^(2)=[(alpha,beta),(beta,alpha)] , then -

If A=[(a,b),(b,a)] and A^(2)=[(alpha, beta),(beta, alpha)] then

If A={:[(a,b),(b,a)]:} and A^(2)={:[(alpha,beta),(beta,alpha)]:} such that beta=Kab . Then the value of K will be___

If A=[{:(a,b),(b,a):}] and A^(2)=[{:(alpha, beta),(beta, alpha):}] then

If A=[(a,b),(b,a)] and A^2=[(alpha, beta),(beta, alpha)] then (A) alpha=a^2+b^2, beta=ab (B) alpha=a^2+b^2, beta=2ab (C) alpha=a^2+b^2, beta=a^2-b^2 (D) alpha=2ab, beta=a^2+b^2

If alpha, beta, gamma are the roots of x^3+a x^2+b=0 then the value of [[alpha , beta , gamma],[beta , gamma , alpha],[gamma , alpha , beta]] is
