Find the square root of the following numbers by the repeated subtraction method 256

Every  square  number  can  be  expressed  as  a  sum  of  successive  odd  natural  numbers  starting  from  1. 

So,  square  root  of  256  =

256  -  1  =  255  ,  

255  -  3  =  252  ,

252  -  5  =  247  ,

247  -  7  =  240  ,

240  -  9  =  231  ,

231  -  11  =  220  ,

220  -  13  =  207  ,

207  -  15  =  192  ,

192  -  17  =  175  ,

175  -  19  =  156  ,

156  -  21  =  135  ,

135  -  23  =  112  ,

112  -  25  =  87  ,

87  -  27  =  60  ,

60  -  29  =  31 

and  finally,  31  -  31  =  0.

We  had  to  subtract  16  odd  numbers  to  obtain  o.

Therefore ,  this  means  that  16  is  the  square  root  of  256.

Find the square root of the following numbers by the repeated subtraction method 256

in repeated subraction method we have to subtract only odd numbers so our first odd no. is 1

256-1=255 -   3=252 -5=247- 7=240 - 9=231-11=220 -13=207 - 15=192 -17=175 -19=156 -21=135 -23=112 -25=87-27=60 -29=31 -31=0

now in total we subtracted 16 odd numbers.So,16 is the square root of 256

To find square root of 256 by repeated subtraction method, which step is 175 and the total number of steps of subtraction is .
