what’s number 10??? plz help

3.7416574

Step-by-step explanation:

3 * 3 = 9

4 * 4 = 16

So we know that we are dealing with decimals because 14 is in-between 9 and 16.

We try all decimals.

3.7 * 3.7 = 13.69

3.8 * 3.8 = 14.44

Now we know it is in-between 3.7 and 3.8.

We try all decimals.

3.74 * 3.74 = 13.9876

3.75 * 3.75 = 14.0625

Now we know it is in-between 3.74 and 3.75

We try all decimals and keep going till we get 14.

When we get 14 we will be doing

3.74165738677 * 3.74165738677 = 14

Then we go to the nearest integer.

3.74165738677 => 3.7416573868 => 3.741657387 => 3.74165739 => 3.7416574 => 3.7416574

Now we can't go anymore. This is our answer.
