    Step-by-step explanation:

    since √5 is an irrational number

    we know that the sum of a rational and irrational is an irrational

    and the difference of a rational and irrational is an irrational number

    so 2 is a rational number and √5 is an irrational number

    then their difference 2-√5 is an irrational number
