Question

p{X:X is a factor of 25} and q={X:X is a factor of 125} find p-q and q-p​

Answer 1

Answer:

i) P-Q = { }

ii) Q-P = {125}

Step-by-step explanation:

P = { x:x is a factor of 25}

= { 1,5,25}

Q = {x: x is a factor of 125}

= { 1,5,25,125}

i) P-Q = {1,5,25}-{1,5,25,125}

= { }

ii) Q-P = {1,5,25,125}-{1,5,25}

= {125}
