whuch two square roots are used to estimate square root 5?

Question

I don't get it

Answer 1

If you want to estimate the √5

then find a square root above and below it.

 

1^2 = 1 , √1 = 1

2^2 = 4 , √4 = 2

3^2 = 9 , √9 = 3

 

So - can you see how the square root of 5 is between 2 and 3?

See how it is closer to the √4 = 2 than to the √9 = 3

So it is a little over 2
