If P(a) denotes the Power set A and A is void set, then n(P(P(P(a)))) is:

Let P(n) denote the statement that n^(2)+n is odd. It is seen that P(n) = P(n + 1). P(n) is true for all.

The line x+ y = 1 meets X-axis at A and Y-axis at B,P is the mid-point of AB, P_1 is the foot ofperpendicular from P to OA, M_1 , is that of P_1 , from OP;P_2 , is that of M_1 from OA, M_2 , is that of P_2 , from OP; P_3 is that of M_2 , from OA and so on. If P_n denotes the nth foot of the perpendicular on OA, then find OP_n .

For any three sets P, Q and R, P-(QcapR) is

If P_(n) denotes the product of all the coefficients of (1+x)^(n) and 9!P_(n+1)=10^(9)P_(n) then n is equal to

If S_n=n P+(n(n-1))/2Q ,w h e r eS_n denotes the sum of the first n terms of an A.P., then find the common difference.

A wire connected to a power supply of 230V has power dissipation P_(1) . Suppose the wire is cut into two equal pieces and connected parallel to the same power supply. In this case power dissipation is P_(2) . The ration (P_(2))/(P_(1)) is.

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