If `(a^2+1)/(a)=4` then show that `(a^6+1)/(a^3)=52`

If (a-(1)/(a))^(2)=3 show that a^(6)+(1)/(a^(6))=110

If a=(1+i)/(sqrt2), "show that" a^(6)+a^(4)+a^(2)+1=0.

If a^3+1/a^3=52 , then the value of 2(a+1/a) is : यदि a^3+1/a^3=52 है, तो 2(a+1/a) का मान क्या होगा ?

If A = [(5,2),(-1,2)] and I = [(1,0),(0,1)] show that (A - 3I) (A - 4I) = 0

If A=[(5,2),(-1,2)] and I=[(1,0),(0,1)] show that : (A-3I)(A-4I)=O

If A= [[5,2],[-1,2]] and I= [[1,0],[0,1]] show that (A-3I) (A-4I)=0

Without expanding determinants show that |(1,3,6),(6,1,4),(3,7,12)|+4|(2,3,3),(2,1,2),(1,7,6)|=10|(1,2,1),(3,1,7),(3,2,6)|

If A=[[1,3,4],[2,6,7]] ,show that (A')'=A
