Is it correct to say that Square Root of 0.9 is 0.9 itself

Question

When I calculate Square Root of 0.9, it comes around 0.9486832980505138. Though I have heard people occasionally saying that the square root of 0.9 is 0.9 itself. Would it be correct to make a statement like this?

Thanks.

Answer 1

The point is that you rounded your answer to $0.9$

But even if you did round, it would be incorrect to say $\sqrt{0.9}=0.9$

The correct statement is that the square root of $0.9$ is approxiamately $0.9$

$$\sqrt{0.9}\approx0.9$$
