Classify each element of `{ sqrt(7), (-1)/(4), 0,3.14,4,(22)/(7)}` as a member of `NN,QQ,RR-QQ or ZZ`.

|(1,4,2),(2,-1,4),(-3,7,-6)|=

Solve : ((4+ sqrt(7)))/3 times ( (4- sqrt7))/3

If A=[(x,1,4),(-1,0,7),(-4,-7,0)] such that A'=-A then x=

Relation R = {(4,5),(1,4),(4,6),(7,6),(3,7)} then R^(-1)OR = .......

The points (2,5,-4) , (4,7,-6) , (1,4,-3) are

If x= (7+4sqrt(3)), prove that x+1//x= 14

sqrt(7+4sqrt3) - sqrt(7-4sqrt3) =

If A=[(2, 1, 3, 4), (5, 9, -4, sqrt(7)), (3, (5)/(2), 8, 9), (7, 0, 1, 4)] then find the element of a_(43)=___ .
