Question

How do you solve `sqrt( x+3)=5`?

Answer 1

`x=22`

Explanation:

Squaring both sides, We get `x+3 = 25 or x=25-3 or x=22` [Answer]

Answer 2

22 :)

Explanation:

We simply do a little algebraic techniques to solve for the value of `x`. First, we must remember the "Golden Rule of Algebra", what ever you do in the one side of the equation, you must do it in the other side of the equation. (Balancing).

`sqrt(x+3) = 5`

we need to isolate the value of `x` to get its value,

to eliminate the square root sign, we need to square both sides, giving:

`x + 3 = 25`

to eliminate the 3 in the Left Side of the Equation, we need to minus `3` in the both sides giving:

`x = 22`

hence, the answer and value of `x` is `22`

Answer 3

`sqrt(x+3)=5`

Square both sides to remove the radical sign:

`rarr(sqrt(x+3))^2=5^2`

`rarrx+3=25`

`rarrx=25-3=2`
