31 paź 2021 · How to: Solve a Radical Equation. Isolate a radical. Put ONE radical on one side of the equal sign and put everything else on the other side. Eliminate the radical. Raise both sides of the equal sign to the power that matches the index on the radical. This means square both sides if it is a square root; cube both sides if it is a cube root; etc.
The parts of this expression are: ) “a” – The ‘index’, or the “root” of the expression. ) “ a ” – The ‘radical’ symbol. ) “ x n ” – The radicand. This expression can be rewritten as a fractional power on ‘ x ’ of the form: x n / a , where a , n∈Z.
1 Radical Equations. An equation that has the variable to be solved for inside a radical is called a radical equation. The algebraic manipulations (described below) needed to solve the equation for the variable can be involved, and may result in extraneous solutions.
Step 4: Translate into an equation by writing the appropriate formula. Substitute in the given information. Step 5: Solve the equation. Step 6: Check the answer in the problem and make sure it makes sense. Does \(5\) seconds seem like a reasonable length of time? Yes. Step 7: Answer the equation.
1. When n is an even number and a>0, n√a>0, called the principal root. When n is an even number and a<0, n√a is not a real number. 2. When n is an odd number and a>0, n√a>0. When n is an odd number and a<0, n√a<0. The n in n√a (always a natural number greater than 1) is called the index or the order of the radical, and a is called the radicand.
