Question 83152: Radical sign and the radicand under it is x - 1 = 3
This is what I got. Let me know, if it is correct.
radical sign and the radicand under it is x - 1 = 3
+ 1 +1
x = 4
radical sign and the radicand under it is x squared = (4) squared
answer = x = 16

sqrt%28x-1%29+=+3 Square both sides.
x-1+=+9 Add 1 to both sides.
x+=+10
-------------------------
sqrt%28x%5E2%29+=+4%5E2 Take the square root of the left side.
x+=+4%5E2
x+=+16
