1. Since √5 is irrational no., then, 2-√5 is also a irrational numbe

2. 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
