To prove that: Negative of an irrational number is irrational
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.
