Answer 2

Step-by-step explanation:

let us consider 5-root 2 is an rational number

where 55-root 2 =p/q where p and q are integers and q not equal to 0 p and q r co prime no

5 -root 2=p/q

5 = p/q+root 2

5 -p/q = root 2

5p -q /q= root 2

we know that 5p -q / is a rational number

but root 2 is an irrational number

there fore 5-root 2 is an irrational number
