Question

Si P= {7x – 5 / x ϵ IN , 0 < x < 3} Q= {x – 6 / x ϵ IN , 7 < x < 11} Halla P x Q

Answer 1

Respuesta:

P= {7x – 5 / x ϵ IN , 0 < x < 3}

                            x = ( 1,2)

7x - 5 = 7(1) - 5 = 2

7x - 5 = 7(2) - 5 = 14 - 5 = 9

P = {2,9}

Q= {x – 6 / x ϵ IN , 7 < x < 11}

                              x = ( 8,9,10)

x - 6 = 8 - 6 = 2

x - 6 = 9 - 6 = 3

x - 6 = 10 - 6 = 4

Q= {2,3,4}

Halla P x Q

{2,9} x {2,3,4}
