Consider the set A = {a, b, c} i. How many elements are there in its power set P(A)? Write the power set P(A).

Write down all the subsets of the following sets : (i) {a} (b) {a, b} (c) {1,2,3} (d) phi

The set does not have proper subset is

Let A = { a, e, i, o, u} and B = { a, b, c, d} . Is A a subset of B ? No. (Why?). Is B a subset of A? No. (Why?)

If a,b,c,d are in geometric sequence then prove that (b-c)^(2) +(c-a)^(2) -(d-b)^(2)=(a-d)^2

If a,b,c,d are in a geometric sequences, then show that (a-b+c) (b+c+d) = ab + bc + cd.

Consider the following sets and fill up the blanks with =or ne so as to make the statement true. A = {1,2,3{} B = {The first three natural numbers} C = {a,b,c,d} D = {d,c,a,b} E = {a,e,I,o,u} F = {sets of vowels in English Alphabet} (i) A....B (ii) A...E (iii) C....D (iv) D....F (v) F....A (vi) D.....E (vii) F.....B
