Question 547702
So we have two options:

Option 1 is:
{{{sqrt(n)=sqrt(100)+1}}}
{{{sqrt(n)=10+1}}}
{{{sqrt(n)=11}}}
{{{sqrt(n)^2=11^2}}}
{{{n=121}}}

OR 
Option 2 is:
{{{sqrt(n)=sqrt(100)-1}}}
{{{sqrt(n)=10-1}}}
{{{sqrt(n)=9}}}
{{{sqrt(n)^2=9^2}}}
{{{n=81}}}


So there are two values that follow the given property.
