Answer 2

how to prove 3-2underroot is irrational ..?

Step-by-step explanation:

let 3-2underroot 5 be a rational number.

▶ 3-2underroot5 = x/y

▶ -2underroot5 = x/y -3

▶ underroot5 = x-3y/2y

.•. here, x-3y/2y is rational so, underroot5 is also rational but it can not be possible.

so it is a contradiction .

and hence it is proved that 3-2underroot5 is irrational .
