![]() Step 2: Combine the factors in pairs of identical factors.Step 1: Write the number under the radical as a product of its prime factors and expand the variables.Consider the radical expression √(100x 4y 6z 3). Let us consider an example of simplifying radical expressions with variables for a better understanding. We factorize the variables along with the numbers. The process of simplifying radical expressions with variables is similar to that of numbers. ![]() Consider the radical expression \(\sqrt\) Simplifying Radical Expressions with Cube Root or Higher Rootįor simplifying radical expressions with cube root or higher roots, let us consider an example. Hence, we have simplified the radical expression √486 as 9√6 and it cannot be simplified more. No further multiplication can be done now. Step 4: Simplify the radical until no further simplification can be done.Step 3: Write the factors outside the radical which have the power 2.Step 2: Write the number under the radical as a product of its factors as powers of 2.Step 1: Find the factors of the number under the radical.We will simplify this radical expression into the simplest form until no further simplification can be done. Simplifying Radical Expressions with Square Rootįor simplifying radical expressions with square root, let us consider an example. We will recall some tricks that we use for simplifying radical expressions such as multiplying and dividing with the conjugate, finding factors in pairs for a square root, etc. Let us consider a few examples for simplifying radical expressions step-wise. Simplifying radical expressions is a process of eliminating radicals or reducing the expressions consisting of square roots, cube roots, or in general, nth root to simplest form. Rules for Simplifying Radical Expressions Simplifying Radical Expressions with Variables Steps for Simplifying Radical Expressions ![]() ![]() In this article, we will learn the steps for simplifying radical expressions with variables and exponents, rules used for simplifying radical expressions with the help of solved examples. Simplifying radical expressions implies reducing the algebraic expressions to the simplest form and, if possible, completely eliminating the radicals from the expressions. The root can be a square root, cube root, or in general, n th root. The radical expressions consist of the root of an algebraic expression (number, variables, or combination of both). Radical expressions are algebraic expressions involving radicals. Let us now recall the meaning of radical expressions. The product of such conjugates will always result in a difference of squares – in the case of multiplying the expressions with a square root term, such product will help eliminate the root.Simplifying radical expressions in algebra is a concept in algebra where we simplify an expression with a radical into a simpler form and remove the radical, if possible. A conjugate pair is, for example, (x – 1) and (x 1) – two expressions that differ only by their sign. In order to eliminate a radical containing a sum or a difference of two terms, one of which is a square root radical, multiply both the numerator and the denominator of a rational expression by a conjugate of the expression in the denominator. In order to eliminate a radical (most commonly a square root) containing a radicand that is a number from the denominator, just multiply both the numerator and the denominator of a rational expression by the radical. It is done so that it is easier to perform further computations involving that rational expression and so that the value of the expression is more obvious. When there is a radical in the denominator, we need to rationalize the denominator that is eliminate the radical expression from the denominator. Radicals can be a part of rational expressions.
