If P={1,2}, form the set `P xx P xx P`

If P={a,b,c} and Q={r}, form the sets P xx Q and Q xx P .

In triangle ABC if p_1, p_2, p_3 are the length of the altitudes from A, B, C then p_1,p_2,p_3

IF p_1,p_2,p_3 are the lengths of the altitudes from the vertices of Delta ABC to the opposite sides, then p_1 p_2 p_3 =

p(x) =x +2. Find p(1), p (2),p (-1) and p (-2). Which among 1,2,-1 and -2 becomes the 0 of p (x) ?

IF p_1,p_2,p_3 are the lengths of the altitudes of a triangle from the vertices A,B,C then 1//p_2^1+1//p_2^2+1//p_3^2=

IF p_1,p_2,p_3 are the lengths of the altitudes of a triangle from the vertices A,B,C then 1/p_1+1/p_2 -1/p_3=

If p_1 ,p_2,p_3 are the lengths of altitudes of Delta ABC from the vertices and Delta is the area of Delta ABC " then " (1)/(p_1) +(1)/(p_2) - (1)/( p_3) =

Let P be the set of all subsets of a given set X. Show that uu:P xx P to P given by (A,B) to A uuB and nn:PxxP to P given by (A,B) to A nnB are binary operations on the set P.
