Answer 2

Answer:

Step-by-step explanation:

there are other ways that you can estimate the square root without using a calculator.

So you know that :

the square of 1 = 1

the square of 2 = 4

And 3 is between 1 and 4 so using simple observation you can conclude that the square root of 3 would be more than 1 and less than 2.

Now if we observe more closely, 3 is more close to 4 than it is to 1. Which means that the square root is more likely to be near 2 over 1.

Then if you know the squares of numbers between 10 and 20 you can easily tell that the square root of 1.5 = 2.25

and 3 is more than 2.25 which indicates that the square root would be more than 1.5.

So till now we are able to tell that

1.5 < square root of 3 < 2

Now you know the square of 1.7 = 2.89

and Square of 1.8 = 3.24

Using that information you can narrow it even further

1.7 < square root of 3 < 1.8

Since 2.89 is more close to 3 than 3.24 is, you can conclude that if you round the square root of 3 it will be 1.7.

I hope that helped

All the best.
