What square root property is essential to solve any radical equation involving square root?
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
radical equations have sq roots, cube roots etc. Quadratic equations have x2.
When in doubt always square both sides of the equation.
The first step is produce the radical equation that needs solving.
The property that is essential to solving radical equations is being able to do the opposite function to the radical and to the other side of the equation. This allows you to solve for the variable. For example, sqrt (x) = 125.11 [sqrt (x)]2 = (125.11)2 x = 15652.5121

If you take an equation such as Ax2+ Bx+c=0, you can complete the square and then use the square root property to solve it. That is how we derive the quadratic equation. For example, x2+2x-9=0 We write this as (x+1)2=10 bu completing the square then the square root property tell us that x+1 is PLUS OR MINUS Square root of 10
Radical...Apex :)

Square both sides of the equation to get rid of the radical sign. Then just solve as you normally would. Good luck! :-)
They are actually to the one half power. You can take a factor in the radical and sqrt it and put in on the outside... Ex. sqrt(28) = sqrt(4 * 7) = sqrt(22 * 7) = 2sqrt(7) sqrt(28) = 2 * sqrt(7)

It often helps to isolate the radical, and then square both sides. Beware of extraneous solutions - the new equation may have solutions that are not part of the solutions of the original equation, so you definitely need to check any purported solutions with the original equation.
