I thinkg you mean:
sqrt%28x-1%29=3
if so...
%28sqrt%28x-1%29%29%5E2=%283%29%5E2
x-1=9
x-1%2B1=9%2B1
x=10
_______________________
Check:
sqrt%2810-1%29=3
sqrt%289%29=3
3=3We're right, unless you meant:
----------------------------------------
sqrt%28x%29-1=3
sqrt%28x%29-1%2B1=3%2B1
sqrt%28x%29=4
%28sqrt%28x%29%29%5E2=%284%29%5E2
x=16

Check:
sqrt%2816%29-1=3
4-1=3
3=3We're right, unless you meant the first way. If so, refer to the above.
