Question

How do you solve `sqrtx = 12`?

Answer 1

`x=144`

Explanation:

If we consider that in order to isolate and solve for an unknown value, whatever we do to one side we must do to the other:

Therefore, if we consider the equation;
`sqrtx=12`
In order to eliminate the square root of `x` and simply express the equation in terms of `x`, we must square both sides - remembering that whatever we do to onside of the equation we must do to the other to maintain the equality of the equation.

`->sqrtx^2=12^2`
`x=144`
