Step-by-step explanation:

Answer 2

How Calculate/Estimate Square Roots:-

1) Break the no. in the terms of nearest square root possible

In this case, we had 2 options

140= 144(perfect sq of 12) -4

140= 121(sq of 11) + 29

but the 1st one was nearest

So we did that

2) Use Formula √x - y/2√x

Like we did 144 - 4 for 140

If u had chosen the 121 + 29 method, then there would have been + in the above Formula

3) Put Values and get exact Square Roots
