We know that 20

^{2}=400We also know that 21

^{2}=441Since 411 is between those two numbers, the √(411) is between 20 and 21.

I hope this helped!

We know that 20^{2}=400

We also know that 21^{2}=441

Since 411 is between those two numbers, the √(411) is between 20 and 21.

I hope this helped!

20^{2} = 400

21^{2} = 441

So the √411 lies between 20 and 21

20 < √411 < 21

Note: By calculator √411 ≅ 20.273135 rounded to 6 decimal places
