Expert Answer:

To prove that:  Negative of an irrational number is irrational

Proof:

Let us assume that negative of an irrational number is a rational number.

Let p be an irrational number,

→ -p is a rational number.

→ - (-p) = p  is a rational number.

But p is an irrational number.

Therefore our assumption was wrong.

So Negative of an irrational number is a rational number.
