MCQ
If $'m\ '$ is a positive integer which is not a perfect square, then $\sqrt{\text{m}}$ is:
- ✓An irrational number.
- BAn integer.
- CA rational number.
- DA natural number.
✓
Answer
Correct option: A.
An irrational number.
In $\sqrt{\text{m}}$ ,if $m$ is not perfect square ,then the value of $\sqrt{\text{m}}$ will be $\text{m}^\frac{1}{2}.$
But if it is perfect square then value of $\sqrt{\text{m}}=$ some integer,
Example $\sqrt{4}=2$
