Question

what is answer of √0.2​

Answer 1

Answer:

Heron's method

To find Square root of 0.2

Make a guess. 0.5*0.5= 0.25

So let's start with 0.5.

Divide the number by the guess.

0.2/0.5= 0.4

Take the average of 0.5 and 0.4 to get 0.45.

This is closer to the square root of 0.2 than the initial estimate.

Repeat the above process.

0.2/0.45= 0.444

Take the average of 0.45 and 0.444 to get 0.447.

This is a fair estimate for the square root.
