Question

Answer 1

√4069

Approximately 63.788

Answer 2

hi i am going to show a nice trick:-

easy way to find square root:-

since 4*4=16 and 6*6=36 ends with 6

$\sqrt{4096}$ ends with 4 or 6.

Find square of which number from 1 to 9 is the closest to  40 which will be 6^2 = 36. So either 64 or 66 can be the square root of 4096.

Now multiply this 6 with its next number 7 which will come as 42. As 40 is smaller than 42, hence the smaller number 64 will be the desired square root.  

So

$\sqrt{4096}$=64
