State which of the following statement are true.
(i) `{}=phi` (ii) `phi=0` (iii) `0={0}`

A is the set of prime number less than 10, B is the set of odd numbers less than 10 and C is the set of even numbers of less than 10. Which of the following statements are true? (i) A subset B (ii) B subset A (iii) A subset C (iv) C subset A (v) B subset C (vi) phi subset A

A= {a, b {c, d}, e} which of the following statements are correct? phi in A

If y+log(1+x)=0 which of the following is true?

State which of the following statements are true and which are false. Justify your answer. 3 in {x |x^(4)-5x^(3)+2x^(2)-112x+6=0}

Examine whether the following statements are true or false : phi sub {x, y, z}

State whether the following statements are true or false. Justify your answers. (iii) Every real number need not be a rational number

State whether each of the following statements are true or false. If the statement is false, rewrite the given statement correctly. (i) If P= {m, n} and Q = {n, m}, then P xx Q= {(m, n),(n, m)}. (ii) If A and B are non-empty sets, then A xx B is a non-empty set of ordered pairs (x, y) such that x in A and y in B. (iii) If A={1,2}, B={3,4} then A xx (B cap phi)=phi

State whether the following statements are true or false. Justify your answers. (ii) Every rational number is a real number.

By giving a counter example, show that the following statements are not true. (ii) q: The equation x^(2) - 1 = 0 does not have a root lying between 0 and 2.
