[" 21) Check whether the relation "R" in set of real numbers defined by "],[qquad R={(a,b):a<=b^(3)}" is reflexive,symmetric,transitive "]

Check whether the relationR in the set R of real numbers defined by : R={(a,b):1+abgt0} is reflexive, symmetric or transitive.

Check whether the relation R in the set R of real n umbers defined by : R = { (a, b), a le b^3} is reflexive, transitive or symmetric.

The relation R, in the set of real number defined as R = {(a,b): a lt b} is:

Check whether the relation R in IR of real numbers defined by R={(a,b): a lt b^(3)} is reflexive, symmetric or transitive.

Check whether the relation R in the set N of natural numbers given by R = { (a,b) : a is a divisor of b } is reflexive, symmetric or transitive. Also determine whether R is an equivalence relation

check whether the relation R in the set N of natural numbers given by R = { (a,b) : a is divisor of b } is reflexive, symmetric or transitive. Also determine whether R is an equivalence relation

check whether the relation R in the set N of natural numbers given by R = { (a,b) : a is divisor of b } is reflexive, symmetric or transitive. Also determine whether R is an equivalence relation

Check if the relation R on set of real numbers, defined as R = {(a,b) : aleb^3} is reflexsive, symmetric or transitive.

Check whether the relation-R defined in the set of all real numbers as R={(a,b): a le b^(3)} is reflexive, symmetric or transitive.

Show that the relation R in the set R of real number defined by R = {(a, b) : a le b }, is reflexive and transitive but not symmetric.
