Write the relation R = {(x, `x^3`) : x is a prime number less than 10} in roster form.

Determine the domain and range of the relation R defined by : R = {(x, x^3): x is prime number less than 10}.

The set of prime numbers less than 100 is :

The set A = {x : x is an odd number less than 10} equals :

Consider the following relations: R = {(x, y) | x, y are real numbers and x = wy for some rational number w}; S={(m/n , p/q)"m , n , p and q are integers such that n ,q"!="0 and q m = p n"} . Then (1) neither R nor S is an equivalence relation (2) S is an equivalence relation but R is not an equivalence relation (3) R and S both are equivalence relations (4) R is an equivalence relation but S is not an equivalence relation

Let A={x: x is a positive multiple of 3 less than 100} and B={x: x is a prime number less than 20}, then n(A) + n(B) is equal to:

Write the following set in roster form: B = {x : x is a natural number less than 6}

Write the following set in roster form: D = {x : x is a prime number which is divisor of 60}

Write the set {x : x is a positive integer and x^2 < 40 } in the Roster Form.

Define a relation R on the set N of natural numbers by R = {(x, y) : y= x + 5, x is a natural number less than 4, x,y in N}. Depict this relationship using roster form. Write down the domain and the range.
