Determine which interval belongs to the number 17 in the root A) (3; 4) B) (4; 5) C) (0; 3) D) (3.5; 4) E) (4.5; 5)

In fact, this is a fairly simple task.

Its only difficulty lies in the fact that it cannot be extracted from the number “17”.

But even here you can simplify the task.

We will find 2 numbers, 1 of which is greater than “17” and 2 of which is less than “17”.

And from these numbers √ will have to be completely extracted.

So let’s start with less. The root is extracted from “16”. This will be “4”.

Now let’s find more. √ is not extracted from “18”, “19”, “20”, “21”, “22”, “23”, “24”.

And from the number “25” is extracted. This will be “5”.

That is, √ of “17” belongs to the interval “B”, is between “4” and “5”.
