विकल्प
True
False
उत्तर
This statement is False.
Explanation:
Let us consider irrational numbers `sqrt(2)` and `root(4)(2)`
- `(sqrt(2))^2 = 2`, which is a rational number.
- `(root(4)(2))^2 = sqrt(2)`, which is an irrational number.
Hence, square of an irrational number is not always a rational number.
