The basic method is the same as for other types of equations: you need to isolate the variable ("x", or whatever variable you need to solve for). In the case of radical equations, it often helps to square both sides of the equation, to get rid of the radical. You may need to rearrange the equation before squaring. It is important to note that when you do this (square both sides), the new equation may have solutions which are NOT part of the original equation. Such solutions are known as "extraneous" solutions. Here is a simple example (without radicals):
x = 5 (has one solution, namely, 5)
Squaring both sides:
x squared = 25 (has two solutions, namely 5, and -5).
To protect against this situation, make sure you check each "solution" of the modified equation against the original equation, and reject the solutions that don't satisfy it.
Radical...Apex :)
It is called solving by elimination.
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
A radical is an exponent, stupid.
Equations = the method
It really is utilized to solve specific variablesIt really is utilized to rearrange the word.
An equation that contains a radical with a variable in the radicand is called a radical equation. These equations typically involve square roots, cube roots, or higher roots, and the variable is located inside the radical symbol. Solving radical equations often requires isolating the radical and then raising both sides of the equation to an appropriate power to eliminate the radical.
Solving inequalities and equations are the same because both have variables in the equation.
Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.

Logic and reasoning are essential in problem-solving and decision-making. For example, in mathematics, using logical steps to solve equations is a form of reasoning. In business, analyzing data and making decisions based on logical deductions is another example. In everyday life, weighing pros and cons to make a decision is a form of logical reasoning.
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)
