In order to find the value of √0.9,

convert the decimal part into fractional part to make the question easier.

So √0.9, would be ==> √9/10,

which further will be equal to 3/√10.

Do the rationalisation part,

and you will get your answer as 0.3(√10).

You can even find the value of √10 and multiply it with 0.3 to get answer without any root value.
