9.1quad a^(2)=2" then "a+1=?

If a^(2) +(1)/(a^(2)) = 2 , then a - (1)/(a) = ?

The sum of infinite terms of the series cot^(-1)(2^(2)+1/2)+cot^(-1)(2^(3)+1/2^(2))+cot^(-1)(2^(4)+1/2^(3))+…=cot^(-1)k then k =

A=[(1,2),(2,1)], then adjoint of A is equal to (A) [(1,-2),(-2,1)] (B) [(2,1),(2,1)] (C) [(1,-2),(-2,1)] (D) [(-1,2),(2,-1)]

If (1//2^1)+(1//2^2)+(1//2^3).....+(1//2^10)= 1//k , then what is the value of k? यदि (1//2^1)+(1//2^2)+(1//2^3).....+(1//2^10)= 1//k है, तो k का मान क्या है?

Let A = (1,2,3) and R = (1,1), (2,2), (1,2), (2,1), (1,3) then R is

If A=[[1, 2, 2], [2, 1, 2], [2, 2, 1]] and A^(-1) exist and not equal to 0, then (A^(2)-4A)A^(-1)=

If A=[[1, 2, 2], [2, 1, 2], [2, 2, 1]] and A^(-1) exist and not equal to 0, then (A^(2)-4A)A^(-1)=
