How to find which expressions given equal a rational number?
Firstly, we know that π is an irrational number .
So π x √4 = 2π
2π is an irrational number and so option A cannot represent a rational number.
2/3 + 4/3 = 6/3 = 2
- Since 2 is a rational number, we can say option b represents a rational number
[tex]\sqrt{36} + \sqrt{5}[/tex]
= 6 + [tex]\sqrt{5}[/tex]
- We, know that [tex]\sqrt{5}[/tex] is an irrational number , So option C cannot represent a rational number.
[tex]\sqrt{3} - \sqrt{3} = 0[/tex]
So, option D represents a rational number.
[tex](\sqrt{49} )(\sqrt{1} ) \\= 7[/tex]
- 7 is a rational number and so option E represents a rational number.
