If the square root of 2x+1=5, then square both sides to get 2x+1=25. Subtract 1 and get 2x=24. Divide by 2, and x=12.

(2x+1)^(1/2)=5
((2x+1)^(1/2))^2=5^2 Square both sides
2x+1=25 Subtract 1
2x=24 Divide by 2
x=12

Do you need to solve for x?
Here it is:
If the square root of 2x+1=5, then
2x+1=25 (square both sides)
2x=24
x=12

sqrt(2x + 1) = 5
2x + 1 = 25
2x = 24
x = 12

If you mean
(2x + 1)^(1/2) = 5
then x=12.
However, if you mean
(2x)^(1/2) + 1 = 5
then x=8.
