Sorted by: 18. The usual reason I've heard is that dividing by integers is computationally easier -- it's easier to find, say, ( 5 3) / 3 by computing 5 × 3 ≈ 8.66 and then dividing by 3 to get 2.89 then

## Rationalizing Denominators

Getting rid of the radical in these denominators involves using the conjugate of the denominators. A conjugate is a binomial formed by taking the opposite of the second term of

## Rationalizing Denominators and Numerators of Radical

When a radical does appear in the denominator, you need to multiply the fraction by a term or set of terms that can remove that radical expression. While the use of calculators

Figure out mathematic equation

Solving mathematical equations can be a fun and challenging way to spend your time.

Determine mathematic equation

Math is the study of numbers, space, and structure.   ## Rationalizing Denominators

For an answer to be in proper format, radicals (square roots) cannot be left in the denominator. The way to remove them from the denominator is to multiply both the numerator and the
`  ## How to Rationalize the Denominator

rational\$sol = Sqrt [1/ ( (x + Sqrt [x^2 + y^2]) (-x + Sqrt [x^2 + y^2]))* (-x + Sqrt [ x^2 + y^2])] // FullSimplify. When I search (e.g., stack exchange ) Simplifying Radicals in

## Removing Radicals from the Denominator

To rationalize a radical in the denominator means to take the given fraction and multiply it by the radical rewritten as a factor of one. Multiplying the radical as a factor of one
