 Hi and welcome to the session. I am Asha and I am going to help you with the following question which says if R is the set of real numbers and Q is the set of all the rational numbers then what is R minus Q? Let us start with the solution. Let us learn some key concept. Now real numbers consist of rational numbers and irrational numbers. Rational numbers are denoted by Q. Also real numbers consist of irrational numbers. And rational numbers are the numbers of the form P upon Q where P and Q are integers and Q is not equal to 0. All those numbers which cannot be written in the form of P upon Q where P and Q are integers and Q is not equal to 0 are irrational numbers. So to find R minus Q where R are real numbers we have to subtract all the rational numbers from the real numbers and on subtracting all the rational numbers from the real numbers we are left with all the irrational numbers. R minus Q is the set of all irrational numbers. So this completes the solution. Hope you enjoyed it. Take care and have a good day.
