TO DETERMINE

x∈{2,3,4} and y∈{4,6,9,10}

TO find the set of all ordered pairs (x,y) such that x is a factor of y

CALCULATION

Let R be the required Set.

Then

 \sf{ R =  \{ \: (x, y)  : x \:  is  \: a \:  factor \:  of  \: y\:  \}}

Here

 \sf{2  \: is \:  a  \: factor \:  of \:  4  \: \:  implies \:  (2,4)  \in R}

 \sf{2  \: is \:  a  \: factor \:  of \:  6  \: \:  implies \:  (2,6)  \in R}

 \sf{2  \: is \:  a  \: factor \:  of \:  10  \: \:  implies \:  (2,10)  \in R}

 \sf{3  \: is \:  a  \: factor \:  of \:  6  \: \:  implies \:  (3,6)  \in R}

 \sf{3  \: is \:  a  \: factor \:  of \:  9\: \:  implies \:  (3,9)  \in R}

 \sf{4  \: is \:  a  \: factor \:  of \:  4  \: \:  implies \:  (4,4)  \in R}

Hence

 \sf{R =  \{ (2,4),(2,6),(2,10),(3,6),(3,9),(4,4) \}}

RESULT

Hence the required Set is

 \sf{=  \{ (2,4),(2,6),(2,10),(3,6),(3,9),(4,4) \}}
